Gas Analyzer Technology Boosts Potential For Converting Biogas To Electric Power

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. …

TDL-based moisture analyzers can offer high return on investment for refinery

Tunable-Diode Laser-based moisture sensors help ensure long catalyst life, reduce operational costs, and offer the lowers overall cost of ownership. Refineries and chemical plants have long been subjected – perhaps unwittingly - to high costs incurred from failure of conventional moisture analyzer to accurately read moisture intrusion in feedstocks and hydrogen recycle streams, vital to optimizing product yield and catalyst life. Because typical analyzers, such as those based on surface absorption or adsorption, employ sensors that are exposed directly to harsh elements in the streams they monitor, timely and accurate moisture readings may be disrupted within a relatively short period of time. The disruptive operational life leads to substantial costs that can range from exorbitant consumables and maintenance to conceivably hundreds of thousands of dollars for premature catalyst recharging or untimely interruption of continuous processes. The innovative employment of tunable …
