Eliminate COS from Upstream and Midstream Process Streams

Merichem Technologies has proven solutions for removing corrosive carbonyl sulfide in pipelines, process equipment, pumps, vessels and tanks before COS is hydrolyzed into H2S and CO2.

THIOLEX: Caustic Extraction of Contaminants

Targets: COS as well as small amounts of H2S, CO2 and RSH

Use: Caustic alone or mixed with MEA hydrolyzes and extracts COS from hydrocarbon, given sufficient contact time.

Applicable Feedstocks:

  • LPG
  • NLG
  • Condensate
  • Naphtha
  • Acid / Sour Gas
  • Off Gas
  • Fuel Gas
  • Natural Gas

AMINEX: Amine Extraction of Acid Gas

Targets: COS as well as small amounts of H2S and CO2

Use: A secondary, lean amine extracts COS from hydrocarbon, given sufficient contact time.

Applicable Feedstocks:

  • LPG
  • NGL
  • Condensate
  • Naphtha
  • Acid / Sour Gas
  • Off Gas
  • Fuel Gas
  • Natural Gas
