Sulfur Recovery Unit (Claus SRU)

In many sulfur recovery units, produced sulfur is stored in liquid form in sulfur pits. Operators are increasingly aware that sulfur pits present potential danger to plant personnel and overall plant safety. It is therefore critically important to monitor H2S in the vapor space of sulfur pits to ensure that it remains below the Lower Explosive Limit (LEL, 4.3% by volume). Additionally, the presence of rising concentrations of SO2 in the sulfur pit vapor space provides an early indication of smoldering fires. Therefore, on-line, continuous monitoring of SO2 can enable detection of such fires before they get out of control.

Backed by over thirty years of process and analyzer experience in sulfur recovery, AMETEK Western Research developed the Model 930 H2S Vapor Space Analyzer for sulfur pit storage applications. The AMETEK-designed Model 930 has been field proven as one of the industry’s most reliable instruments for monitoring H2S and SO2.
