By accurately and instantly pinpointing the presence of moisture, HCl, H2S and other impurities, the tunable diode laser (TDL) based gas analyzer (photo) provides significant benefits, including: the prevention of foreshortened lifespan of costly catalysts; enhanced assurance of product quality; reduced turnaround recovery times; and avoidance of unscheduled shutdowns. For H2S analysis, the analyzer can be used, for example, for measuring sour gas headed for processing and sweetened gas coming. Because it is faster than conventional techniques, the TDL-based device can improve process control by letting operators know how much processing is needed. — Booth 2248 — SpectraSensors, Inc., Rancho Cucamonga, Calif.
