Sulfur Recovery Unit (Claus SRU)
The Model 931 is a rugged, single component photometric gas analyzer housed in an explosion-proof (or optional Division 2) package designed for a variety of gas monitoring and process control applications.
Whether it’s reliable high concentration H2S analysis for feed-forward control of modern SRU plants, monitoring of sour gas pipelines, or process control of SRU tail gas treating plants, the Model 931 single gas analyzer is the best choice for reliable, field-proven, and rugged single species measurement applications. The Model 931 analyzer system is available with a heated cell option to avoid any hydrocarbon or water condensation. A fully integrated AMETEK Process Instruments sample system ensures reliable dew point control without running the risk of plugging, contaminating, or flooding the analyzer. The Model 931 may be designed to incorporate additional sensors capable of detecting non-UV absorbing species, such as CO2 (for H2S/CO2 measurements in SRU feed gas) or H2 for H2S/H2 measurement in SCOT type contactor overhead applications). No matter what the need is, this flexible, low maintenance analyzer design is the answer to many of today’s complex process control requirements.
