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 …
