  • Innovative process- SO2 Multi-point injection for SRU test

    7 Process Testing and Results A small test skid was fabricated and installed in a Claus Sulfur Recovery Unit to verify the viability of SO2 Multi-point injection to increase the processing capacity of the Claus unit. The only modification of the SRU for testing was to install tie-ins for the SO2 injection as depicted on page 6. Above.

  • The Claus Sulfur Recovery Process — Sulfur Recovery

    The Sulfur Recovery Unit (SRU) is based on the modified Claus Process, which is a two-step reaction scheme overall. A portion of the total H2S is burned in the Reaction Furnace to form SO2. Then, the H2S and SO2 react, at an optimal 2:1 ratio, to form elemental Sulfur (Sx) across the Claus Reactors.
