Sulfur Recovery Unit (SRU) Debottlenecking

SO2Clean: for Sulfur Recovery Unit (SRU) Debottlenecking

 

Increasing sulfur recovery capacity has become more important with the economic benefits derived from utilizing higher sulfur crude and the never ending push toward cleaner, low sulfur fuels.  Historically, refiners needing to double capacity have added SRUs or debottlenecked existing units through O2 enrichment which requires major reengineering/reconstruction. Both are unattractive options given exorbitant capex and footprint/infrastructure limitations. There is another, better way to debottleneck… direct injection of high purity SO2 into the SRU!

  • Dramatically less capex and no impact on refinery footprint… less execution risk
  • Removes inert gases in air like nitrogen which rob capacity and create NOx emissions
  • Mitigates the high temperature risks of O2 enrichment
