Do you have hard-to-handle gases?

摘要

Gas development projects face growing challenges—increasingly contaminated resources, tightening sales specifications and stricter environmental emission standards. CO2, H2S, H2O, carbonyl sulfide (COS), mercaptans (RSH) and organic sulfides are generally removed from the gas prior to sale or liquefaction. This may result in complicated treating process line-ups, often requiring multiple process units. Technology development or smart integration of different process steps offer many opportunities for line-up simplification. A key unit in these line-ups is the acid-gas removal unit (AGRU), which traditionally relies on amine-based solvent absorption.
