Sulfur Recovery Units typically utilize CLAUS technology to recover sulfur in off-gases from refineries, gas plants, coal gasification or other processes. CLAUS units can be stand-alone, or followed by other sulfur recovery technologies, termed Tail Gas Treaters. The SRU Tail Gas is most often incinerated, converting H2S to SO2, sent through a waste heat boiler and out to the stack.

Challenges in the SRU Tail Gas Clean Up application are:

  • Potentially very high inlet SO2
  • Variable gas flow and inlet SO2 concentrations due to the need to bypass processes downstream
  • High inlet temperatures if a waste heat boiler is not required.
  • Regulators sometimes require system redundancy
