Fluorescence Quenching Eclipses Conventional O2 Measurements in Natural Gas Pipelines

Jennifer Soto — Wed, 03 Feb 2010 22:00:00 GMT

For as long as anyone can remember, Oxygen (O₂) has been a problem in natural gas pipelines, especially when high levels of H₂S are present.

Measurement of O₂ has always come with its own set of issues: maintenance costs, inaccuracies, and reliability. But all that is changing with the introduction of a new technology…Fluorescent Quenching.

Based on a proven technology in the bio-tech world, it uses a sensor (optical probe) that contains an indicator dye sensitive to O₂. The dye is optically excited by an LED light source. The fluorescence emission of the indicator dye decays at a known rate, but if oxygen is present an energy transfer occurs and “quenches” the fluorescence, hence the name, Fluorescent Quenching.

Advantages over traditional measurement include greater accuracy, much faster response, simplified calibration, and virtually no maintenance. There is also no need for a scrubber and the net result is lower overall operating costs.

The sensor is not affected by even high levels of H₂S and there is no cross sensitivity to contaminants or other gases found in natural gas.

Larry Ewing, the owner of Ewing Energy Consulting of Tulsa, Oklahoma, is an expert in gas quality measurement technology. He see’s a wide range of potential applications in natural gas pipelines for Fluorescent Quenching. “It is ideal technology for any area that has H₂S concentration such as sour gas monitoring, production areas, and pumping stations.”

SpectraSensors of Houston, Texas, recently introduced the OXY4400 optical oxygen analyzer for natural gas pipelines using this technology. SpectraSensors has pioneered the use of optical analyzers with its Tunable Diode Laser units that are used world-wide in the industrial process and environmental monitoring markets.

The OXY4400 oxygen analyzer is a compact, stand-alone, one-channel meter with LCD display and data logger. The unit uses a light source (LED), an optical sensor probe and a photo detector. Pulsed light from the LED is sent down a fiber optic cable to the sensor probe (optode) where the energy from the light is absorbed by an indicator dye. The light (fluorescence emission) is sent back through the cable to the photo detector, where it is converted to an electrical signal that can be read.

The amount of “quenching” is determined by the amount of O₂ in the stream. The result is an exact and almost instant measurement down to 0.5 ppm.

Accuracy

Conventional membrane sensors (Clark Cells and Galvanic Cells) can be destroyed by high levels of hydrogen sulfide in the stream. For this reason, they require a scrubber to absorb the H₂S. But when the scrubber becomes saturated the sensor loses it accuracy. In addition, traditional sensors use an electrolyte solution that is “self-consuming” caused by an electrochemical reaction to the oxygen concentration. But that consumption degrades the sensor (similar to a battery) over time forcing users to perform constant calibration. Once these trace oxygen sensors are exposed to high levels of O₂ it can shorten the life or destroy the sensor which must be purged and that can take a long time.

All of this adds up to high maintenance costs and replacement parts to keep membrane sensors accurate.

Fluorescent Quenching offers new levels of accuracy. It does not consume O₂ and needs no scrubber, in fact, it reads the O₂ without being affected by the hydrocarbons or sulfur content. Optical response time is measured in seconds, not minutes.

Since there are no moving parts or electrolytes, there is no need for constant calibration once it is installed. The optical sensor is also unaffected by EMI, shock, or vibration.

Cost Comparison

Initial costs of the OXY4400 are higher than the cost of a traditional system. But the total cost of ownership over the first year is much less than a membrane system. The difference comes from the elimination of constant maintenance and replacement parts for Galvanic cell or Clark cell units. In addition, the cost savings of the optical measurement increases over the lifetime of the instrument.

“It’s a ten-fold savings in cost of ownership compared to membrane technology,” adds Ewing, “and the reliability is much higher. Just think of the late night maintenance calls when an O₂ spike sets off an alarm. Membranes take hours to recover, the optical sensor recovers immediately. There is no need for a maintenance operator to stay on task for hours testing for a gas that isn’t there just because his antiquated sensor has not recovered yet to give him an accurate reading.”

Sam Miller of SpectraSensors sees a host of applications for the OXY4400. “This technology transforms oxygen measurement in the natural gas industry due to its long-term stability. This is especially important for remote locations.”

Laser-based analyzer

Jennifer Soto — Mon, 24 Aug 2009 18:00:00 GMT

A new H2O moisture and analyzer technology is available that employs tunable laser diode (TDL) spectroscopy to provide highly accurate and virtually instantaneous measurements of trace amounts of a particular gas (H2O in this instance). By its nature, the TDL based gas detection method is not susceptible to aging affects, making its factory calibration a timeless constant. The result is a very low maintenance analyzer that does not require consumables or scheduled calibration.

TDL-based analyzers have revolutionized the measurement of gases in petrochemical streams such as natural gas. The technology employs a simple measurement that uses a fundamental principle: molecules vibrate when excited by light at specific wavelengths.

TDL-Based Analyzer Eliminates Costly Problems of Inaccurate Acetylene Measurement

Jennifer Soto — Tue, 30 Jun 2009 19:00:00 GMT

One of the most problematic of those impurities is acetylene (C2H2), which can be difficult to measure accurately using conventional analyzers, and can also drift off spec due to slow analyzer response.

Because it is one of the more problematic contaminants that can spoil ethylene production, acetylene is removed from the ethylene during the purifying proves via the Acetylene Converter Unit. This series of reactors converts the acetylene in the hydrogen to form ethylene. When performing accurately, the converter reduces the amount of acetylene down to low PPM or even PPB levels as required.

“Acetylene hinders and damages the catalyst used in the chemical reaction to form polyethylene,” says Al Kania, a veteran of the petrochemical industry. “A big part of the problem is that acetylene, like moisture, is a component that is very difficult to measure accurately through chemical analysis. Also, the few tools that were previously available, such as the gas chromatograph, were unable to go very low in terms of sensitivity.”

Today, however, there is a technology for accurately measuring acetylene content in ethylene. That technology is a sophisticated application of the tunable diode laser (TDL), that was first developed by NASA to measure gas species even in extremely low concentrations.

TDL versus GC

There are several advantages of the TDL-based analyzer over the gas chromatograph (GC), which has been the primary tool for measuring acetylene and other impurities in ethylene until now.

To begin with, the TDL analyzer is extremely accurate, and remains so for the life of the analyzer. It is quite capable of measuring the concentrations of acetylene and other impurities at sub parts per million levels. The TDL analyzer, developed by NASA-spinoff SpectraSensors, Inc., Houston, TX, has become a state-of-the-art tool for accurately and continuously measuring very low levels of moisture, H2S and other impurities in hydrocarbon streams for several years.

The accuracy of the TDL analyzer is especially applicable to measuring acetylene impurities in ethylene today, not only because ethylene is such a valuable commodity, but also because excessive levels of such impurities will corrupt downstream uses of the ethylene.

“In the past, processors used to be able to tolerate a fair amount of acetylene in ethylene. But in polyethylene production, the presence of acetylene above stringent PPM and sometimes PPB levels is unacceptable and creates very expensive waste,” adds Kania.

If an acetylene converter unit operates too aggressively, he says, it could hydrogenate some of the ethylene back into ethane. So, the proper operation of the unit requires the fast and precise monitoring of acetylene in between the first of the two acetylene reactors (mid-bed) and as it exits the final reactor.

In addition to dependable and repeatable accuracy, the speed of measurements is vital to maintaining consistent purity in ethylene production. TDL analyzer offers the advantage of very high-speed readings.

When using the GC technology, the readings are relatively slow, commonly taking from 3 – 6 minutes to provide measurements. Conversely, the TDL analyzer provides almost continuous readings, with intervals taking only from 1-4 seconds.

“When you’re producing a lot of ethylene every day, acetylene and other impurities can swing on you very quickly,” Kania explains. “If you are unaware of those impurities for several minutes, which happens with the GC, you don’t have a chance to reroute the corrupted offspec ethylene. Also, it will take many hours of production, perhaps days, to purge it out of their downstream units. That’s an expensive proposition. On the other hand, the TDL analyzer measures the ethylene as it is manufactured to ensure it is of a very high purity.”

Beyond measurement

In addition to high-speed accuracy, the TDL laser offers ethylene producers other significant benefits over the traditional GC technology.

GCs are traditionally very complex mechanically, and require a lot of labour-based maintenance, Kania says. They also require a lot of consumables in order to maintain proper operation. However, the TDL analyzer requires very little maintenance and no consumables.

“In the past this was not so much of an issue because the ethylene was so valuable that processors simply bit the bullet and put in whatever resources were necessary,” explains Kania. “But the TDL analyzer requires only periodic maintenance, which adds to valuable uptime. And it does not use consumables, which may be secondary, but also adds to the high ROI.”

Another advantage of the TDL analyzer is the ability of ethylene producers to standardize on equipment. In addition to acetylene, there is an assortment of contaminants they need to monitor, and the TDL analyzer is an ideal solution for a large number of these contaminants.

The SpectraSensors analyzer, for instance, measures H2O, NH3, H2S and CO2 as well as acetylene. It is possible for users to standardize on SpectraSensors analyzers, operating them from the same control center.

“When they use multiple units for various contaminants they can roll up the measurements,” Kania says. “By doing this they not only upgrade their analyzer systems but also create more stable operations so that they don’t have to worry about these impurities or over purifying.”

The SpectraSensors H2S, H2O & CO2 3-Pack gas analyzer systems retain the analytical benefits and reliability known by existing TDL users. Training, support, installation costs, space and overall complexity are reduced by employing one technology for all measurements.

The gas measurements are not affected by glycols, methanol or other corrosives. There is no need for light source or probe replacements, no tape, no carrier gas, and no field calibration.

The system includes all required sample conditioning and regulation. The sample system is heated to 50°C (122°F) to keep all constituents in vapor phase.

Purifying Ethylene With More Precision

Jennifer Soto — Wed, 20 May 2009 21:00:00 GMT

Excessive acetylene contaminants in ethylene make that valuable commodity unusable for polyethylene production. Fast, repeatable and dependable, the laser-based analyzer constantly measures acetylene contaminants during ethylene production, assuring high-quality product while eliminating costly waste.

The purity of ethylene feedstock is critical to the quality of a wide range of petrochemical products, particularly polyethylene plastics. Yet, periodically there are problems when contaminant concentrations exceed stringent purity specifications, rendering valuable ethylene feedstock unacceptable for use in producing such materials. One of the most problematic of those impurities is acetylene (C2H2), which can be difficult to measure accurately using conventional analyzers, and can also drift off spec due to slow analyzer response.

Because it is one of the more problematic contaminants that can spoil ethylene production, acetylene is removed from the ethylene during the purifying process via an acetylene converter unit. This series of reactors reacts hydrogen with acetylene to form ethylene. When performing accurately, the converter reduces the amount of acetylene down to low parts per million (PPM), or even parts per billion (PPB), levels as required.

“Acetylene hinders and damages the catalyst used in the chemical reaction to form polyethylene,” says Al Kania, a veteran of the petrochemical industry. “A big part of the problem is that acetylene, like moisture, is a component that is very difficult to measure accurately through chemical analysis.

Making Analyzers that Work in the Real World

Jennifer Soto — Thu, 01 Jan 2009 20:00:00 GMT

If you work in a process plant, you probably have had some frustrating experiences with analyzers. They’re vital to process measurement and control, but keeping them running can be a real pain. Why can’t someone make an analyzer that works as well and as reliably as a pressure, a temperature or a flow transmitter?

The problems with analyzers are twofold. First, the measurements that have to be made are often a complex and frequently involve chemical reactions. Analyzing chemical composition is always going to more difficult than measuring pressure.

Seconds, many analyzer vendors have roots in making lab instruments for controlled and continuously monitored environments. Adapting these analyzers for on-line operation and field installation while making them rugged enough to not need daily maintenance has been too high a hurdle for many lab instrument vendors.

Now, new entrants from completely different industries are making their mark. For examples, SpectraSensors (www.spectrasensors.com) was started in 1999 to commercialize products adapted from NASA/Caltech Jet Propulsion Laboratory. Because the original products were designed for mission-critical aerospace applications, high reliability and low maintenance were a given.

The challenge was to adapt these aerospace-quality analyzers for industrial use and make them affordable. So, SpectraSensors focused on optical, laser-based gas analyzers for energy and petrochemical industry applications.

The company’s tunable diode laser (TDL) technology measures moisture and carbon dioxide. SpectraSensors also provides custom configurations for measurement of other compounds, such as methane, acetylene, ammonia, hydrogen chloride, hydrogen sulfide, carbon monoxide and nitrogen monoxide.

A leading application for SpectraSensor’s TDL analyzer is in refinery catalytic reformer units. These units convert naphtha streams into higher octane aromatic compounds that can be used in gasoline blending or chemical plants.

All of these compounds must be accurately measured and controlled, or their concentrations can increase until they poison the catalysts in the reactors. Hydrogen sulfide and ammonia must be minimized, while the right balance of moisture and hydrogen chloride must be maintained to extend the time between catalyst regeneration cycles and improve yields.

“All of the measurements can be performed on-line with TDL analyzers, which require less maintenance and are more reliable than previous methods,” says Bill Jenko, SpectraSensors’ director of process product line management.

“The most compelling is hydrogen chloride measurement, which typically is done manually with stain tubes, a handheld off-line measurement method subject to operator-induced variability. Some refineries use stain tubes to measure sulfur and ammonia as well. The ability to move these measurements from manual off-line to continuous on-line reduced operational costs, and improves the production of the reformate and the hydrogen,” adds Jenko.

Concentrations measured vary by application, but a typical dual-range analyzer might measure 0 ppm to 50 ppm and 0 ppm – 1,000 ppm hydrogen chloride.

“Some plants have existing on-line analyzers for moisture measurement, but I haven’t heard of any other proven technology for on-line hydrogen chloride or ammonia measurements in these streams,” claims Jenko.

Jenko says TDL has some advantages that improve reliability and reduce maintenance. “TDL analyzers require no carrier gas or other consumable gases, and this lowers cost of ownership over other technologies. TDL hydrogen chloride and ammonia analyzers need a scrubber because they’re based on differential spectroscopy, but the scrubbers are the only consumable and typically last at least a year.”

TDL Technology Promises Improved Process Control in Gas Plants

Jennifer Soto — Fri, 05 Dec 2008 19:00:00 GMT

Confronted with increasing costs and product integrity issues, the hydrocarbon processing industry has become increasingly dependent on sensors for detection and measurement of impurities in gas streams. For some sensing technologies this can be a hit and miss situation that can compromise process control and result in costly actions including high maintenance costs, unplanned shutdowns and unanticipated shut-ins where the buyer can block the seller from shipping gas.

Gas processing plants require fast and accurate measurements of moisture (H2O), hydrogen sulfide (H2S), and carbon dioxide (CO2) because these contaminants damage expensive equipment such as turbo-machinery and pipelines, shorten desiccant, contactor, or mole sieve lifetimes, and threaten the operator’s ability to maintain tight process control and product quality. In some cases, the gas processor’s downstream customer can shut in their supplier which costs hundreds of thousands of dollars. Tunable Diode Laser (TDL) based analyzers are increasingly being used in these “pain-point” analytical applications to measure contaminants reliably while reducing maintenance and operating costs. TDL absorption spectroscopy employs a laser mounted behind a window that protects it from the wear and tear of caustic gas contents, while enabling the analyzer to accurately and quickly read varying gas concentrations. The laser does not come into contact with the gas and calibration does not change or drift over time (Figure 1 and 2).

Dependable H2O Analysis

Impurities such as moisture and corrosive acids found in many gas streams are the nemesis of conventional sensors, which are directly exposed to the gas stream and those harmful elements. Over time—and sometimes within a few weeks— those probes become damaged and inaccurate, resulting in costly repair or replacement. In the meantime, corrosion and contamination from problematic impurities can damage equipment, catalysts, desiccants and processes.

The TDL-based analyzer allows the gas processors, whether they are sweetening, dehydrating, or removing various impurities, to monitor and measure the inputs and outputs of their processes for CO₂, acids, moisture and H₂S. Furthermore, it accurately takes repeatable measurements within seconds, whereas conventional devices often take many minutes.

Excessive dehydration costs may be incurred because of inaccurate moisture readings or concern on the part of the operator that the gas may be too wet. In many cases, it is necessary to over-process the gas in order to achieve quality specs for multiple customers when taking into consideration the risk of inaccurate measurements and potential false shut-ins. The availability of a fast and reliable measurement allows the plant to confidently deliver gas that is within specifications.

The TDL-based technology is very fast and does not drift, thereby enabling operators to keep dehydration costs to a minimum—without fear of a shut-in. (Figure 3)

Accurate H2S Sweetening

For monitoring and measuring H₂S in gas streams, lead acetate tape analyzers are frequently the technology of choice. In that design, gas is sent directly through the lead acetate tape, which changes color when reacting with sulfur. The system analyzes the color change with a photometer. However, the lead acetate tape is a consumable that is directly exposed to the gas stream. Tape reels must be changed periodically (weekly or monthly), and if there is a system leak, it exposes the whole tape. Also, the used tape is considered hazardous waste, and must be disposed of accordingly.

Some processors use a UV photometer for measuring H₂S. Natural gas may have varying percentages of methane, propane and possibly more than a dozen other components. The measurements results of UV photometers are susceptible to gas composition changes. When the background matrix of the gas changes, that often causes erroneous readings and consequential problems.

For H₂S applications, the TDL-based analyzer measures sour gas going into processing, and sweetened gas coming out. Fast analyzers enable better control of processes by letting the processor know instantly how much processing is needed and provides for faster shut-off when the sweetened gas is not up to required standards. Changes in gas concentrations can be seen immediately with TDL analyzers preventing false alarms, false readings and unwarranted shutdowns.

LNG Applications

The presence of even trace amounts of H₂O or CO₂ can threaten the integrity of processing equipment during compression and liquefaction of natural gas due to ice formation. It is essential to have very fast H₂O or CO₂ detection in order to improve the life of the desiccant while retaining product quality.

In the past, LNG (liquid natural gas) and NGL (natural gas liquids) gas processors have relied on surface based analyzers such as electrochemical and quartz crystal cells to measure trace amounts of moisture in process streams. Although these devices may perform with acceptable accuracy at first, the confidence level in their measurements soon becomes low, due to drift, the inability to read high concentrations of moisture, and the tendency for their sensor probes to become desensitized by the gas streams they are measuring. Such situations have led to excessive maintenance and high operational costs.

The TDL-based gas detection method does not experience aging effects, making its factory calibration a timeless constant. The result is a very low maintenance analyzer that does not require consumables or scheduled calibration.

Emphasis on Process Industries

Although TDL-based analyzers have been widely accepted by the natural gas production and pipeline transmission industry, this technology is fairly new to the process industry. However, because the need for improved process control and reduced costs are equally if not even greater among processors, there has been immediate interest in applying this technology throughout the petrochemical industry. Thousands of TDL analyzers are now installed at operations from off shore production to processing and refining, to chemical plants and emissions monitoring.

Gas Analyzer Technology Boosts Potential For Converting Biogas To Electric Power

Jennifer Soto — Sat, 01 Nov 2008 14:00:00 GMT

The ability of advanced, laser-based sensors to detect moisture, hydrogen sulfide and other contaminants in gases can smooth the way for biogas as a resource for electric utilities.

Wouldn’t it be great if some of the expensive green power programs you hear about actually worked? Experts and financiers are predicting it will take billions of investment dollars and decades to get any meaningful quantity of energy from alternative resources.

Perhaps not. One of the oldest and most widespread forms of potential energy — methane gas — promises to give those efforts a sizable boost — right now.

The main component of “natural gas,” methane is found in abundance in many places other than subterranean gas wells. Landfills, oil pipelines, pasturelands, forests and waste treatment plants all contain methane or the biomass from which methane can be formed.

“Although methane gas contains plenty of energy, until recently the gas available from many sources has been considered economically unviable as a source of energy,” explained Sam Miller, a senior official with SpectraSensors, Inc., Houston, TX.

“Whatever the source of methane, you have to get it to market, which often means getting it into a pipeline that delivers gas to users such as power plants and industrial companies,” he said.

Transporting and marketing methane through pipelines requires that it meet safety and quality standards, Miller said. Virtually all biogas contains significant amounts and varieties of impurities that must be removed before pipelines will transport it and customers will accept it. Such impurities can disrupt the flow of gases, damage pipelines and contaminate the air with toxins that can be deadly to breathe.

PG&E Harnesses Cow Power

Last spring BioEnergy Solutions, Bakersfield, CA, launched California’s first biogas-to-pipeline injection project in Fresno County, central California. The project is using renewable natural gas derived from animal waste at a PG&E site.

“With nearly 2 million dairy cows in California, there is great potential for the state’s agriculture and power sectors to work together to address the challenges of climate change,” said Roy Kuga, vice president of energy supply at PG&E. “This project is yet another example of our company’s commitment to add innovative forms of clean renewable energy to help meet our customers’ future power needs.”

PG&E is one of California’s largest investor-owned utilities. The state’s recently enacted Renewable Portfolio Standard (RPS) Program requires each utility to increase its procurement of eligible renewable generating resources to achieve a goal of 20% of load by 2010. The RPS Program was passed by the California Legislature and is managed by the CPUC and California Energy Commission.

Under a long-term contract approved by the California Public Utilities Commission (CPUC), BioEnergy Solutions will deliver up to 3 Bcf of renewable natural gas a year to PG&E. Using SpectraSensors’ laser-based gas analyzer technology, this is the first project in California to deliver pipeline-quality, renewable biogas to a utility.

“We are using these analyzers to monitor moisture in the methane,” said David Albers, BioEnergy Solutions president. “And of course we’re checking for hydrogen sulfide content and carbon dioxide content.”

Albers said the project, located in the town of Riverdale in western Fresno County, will use manure from the Vintage Dairy’s 5,000 milk-producing cows and calves. The waste is flushed into a covered lagoon — equal in size to the area of nearly five football fields and over three stories deep — that traps the methane gas produced as the manure decomposes. The biogas is upgraded, or “scrubbed,” to remove corrosive materials to meet PG&E’s industry-leading environmental standards for power plants and then delivered to PG&E through the utility’s pipeline.

PG&E uses the natural gas to deliver renewable electricity to its customers in central and northern California. The methane production system also reduces emissions of methane, a greenhouse gas 21 times more potent than carbon dioxide, by 70%.

Albers said SpectraSensors moisture analyzer offers assurance that the project will continually meet PG&E’s high standards. He said that in addition to offering the highest reliability of gas analyzers, this technology has a track record for considerably lower maintenance costs in both labor and consumables.

PG&E, a leader in utilizing biogas, is also a user of SpectraSensors technology. In addition to the utility’s contract with BioEnergy Solutions, it is working to cultivate the next generation of biogas technologies through its biomethanation research project.

Depending on what impurities might be contained in “polluted” gas — substances such as H2O, H2S, CO2, unsaturated hydrocarbons and glycols — it is vital to use monitoring equipment that can accurately read the levels of contaminants in gas streams.

The “gas analyzer” technology needed to quickly and accurately measure a wide variety of contaminants and background gases has been advanced to new heights by SpectraSensors, which makes Miller optimistic about the safety and economic viability of using non-standard sources of methane and other biofuels.

“There has been a significant rise in activity in production and distribution of ‘green gas’ as an alternate fuel,” he said. “Our company considers this a growth market. And while a primary market for our analyzer instruments include pipeline-quality natural gas from traditional producers, we can also help nontraditional producers deliver clean methane to various power generation customers.”

Miller cited several examples of sources for methane, which together could amount to a very sizable reduction of greenhouse gases as well as renewable resource for generating electric power for a grid that every year experiences added demand and will soon have to accommodate plug-in passenger cars.

“Waste-to-energy methane from human and livestock digesters has the potential to become a major source,” he said. “But other, smaller sources are becoming increasingly viable. For instance, the methane gas pockets present in pipeline oil have traditionally been burned off when it reached the oil refinery. Now, it is economically feasible to feed that gas into a gas pipeline and use it to generate electricity.”

The patented technology that SpectraSensors employs in its gas analyzers is tunable diode laser (TDL)-based absorption spectroscopy. This is an optical measurement technology used to detect moisture (H2O), carbon dioxide (CO2), hydrogen sulfide (H2S), ammonia (NH3), oxygen (O2) and more.

In the traditional natural gas production and pipeline market this technology has become the de facto standard for ensuring consistently accurate readings in gas streams. Not only is it in use among many leading pipeline operators, but is also the technology of choice among leading utility companies.

Fast, Accurate And Lower In Costs

Essentially, the SpectraSensors TDL-based gas analyzer uses laser (light) absorption spectroscopy to identify and measure one or more gases in a flow of mixed gases. This type of analyzer is typically “tuned” to monitor a target gas (e.g. H20, CO2, H2S) by monitoring the absorption of light at wavelengths specific to the target gas.

The SpectraSensors gas analyzer line is designed to provide extremely fast and accurate readings without expensive labor and replacement costs. That is because the gas is analyzed away from the stream in a sample cell. As the laser light passes through the gas sample in the cell, the presence of any target gas is detected and its concentration measured.

“This design is very process worthy,” said Miller. “The TDL-based analyzer technology has proven to be so reliable and trustworthy that it is the new standard in the natural gas pipeline industry, and is being adopted by oil refineries, petrochemical plants and process industries all over the world.”

Improving Process Control with TDL Technology

Jennifer Soto — Wed, 01 Oct 2008 19:00:00 GMT

Confronted with increasing costs and product integrity issues, the hydrocarbon processing industry has become increasingly dependent on sensors for detection and the measurement of impurities in gas streams. For some sensing technologies, this can be a hit and miss situation that can comprise process control and result in costly actions, including high maintenance costs, unplanned shutdowns and unanticipated shut-ins.

Protecting expensive process equipment

Gas processing plants require fast and accurate measurements of moisture (H2O), hydrogen sulphide (H2S) and carbon dioxide (CO2), because these contaminants damage expensive equipment such as turbo-machinery and pipelines; shorten desiccant, contractor or molecular sieve lifetimes; and threaten the operator's ability to maintain tight process control and product quality. In some cases, the gas processor's downstream customer can shut in their supplier, which costs hundreds of thousands of dollars.

Every day, weather forecasters are challenged to accurately assess the potential for severe weather such as flooding, hurricanes, and tornadoes, as well as helping to ensure the safety of commercial and private aircraft from threatening thunderstorms, icing and wind shear. On average, more vaporized water (in the form of vapor and clouds) flows over the dry state of Arizona than flows down the Mississippi river. It is this high-energy atmospheric moisture that provides severe weather systems the majority of their strength. Since the 1940’s, a network of about 70 weather balloon stations across the country have collected information about the atmosphere at twelve-hour intervals. They provide the basic weather measurements from the ground up through the jet stream, the layer of the atmosphere where our weather forms. But weather moves quickly, and a snapshot of the atmosphere just a few hours old can become misleading and unrepresentative. This loss of awareness of the...

SpectraSensors Introduces OXY4400 for Trace Measurement of Oxygen in Natural Gas

noemail@spectrasensors.com — Mon, 09 Nov 2009 07:00:00 GMT

Houston, TX (PRWEB) November 9, 2009 -- SpectraSensors, Inc., a leading supplier of optical sensors for petrochemical applications, announced the model OXY4400 oxygen analyzer for natural gas pipelines. A common problem associated with the production of natural gas is the presence of oxygen which can enter via air leaks in upstream equipment. The negative impacts of oxygen in natural gas include corrosion of piping, reduced life of gas plant equipment and penalties on the prices of the gas. Operators control oxygen in natural gas by eliminating leaks, however levels of 10 to 100 ppmv (parts per million by volume) are common. The measurement of oxygen at these low concentrations has been difficult in the past because available technologies suffer damage from corrosive constituents in the gas such as H2S and the sensors themselves decay over time. The maintenance and repair of equipment in these applications is expensive. Natural gas production and gathering sites are typically...
