Sulphur Recovery (Claus process)

Sulphur recovery - Claus processHydrogen Sulphide (H2S) is a byproduct of processing natural gas or refining high-sulphur crude oils. The Sulphur Recovery Process (Claus Process) recovers elemental sulphur from gaseous hydrogen sulphide. Optimisation of sulphur recovery requires precise control of the sulphur ratio H2S/SO2 in tail gas. The measurement is used as as feedback to determine the dosage of raw acid gas and air.
Key measurements include:

  • H2S (hydrogen sulphide) high concentration - for raw acid feed gas measurement

  • H2S (hydrogen sulphide) low concentration - for Claus tail gas measurement
