Amine Gas Sweetening

Acid gases must be removed from the process gas due to pipeline transmission or process requirements, cryogenic processes, or corrosion mitigation. Amine treating includes two operations: 1) absorption of the acid gas into the amine solution and 2) regeneration of the rich amine solution through heat and steam stripping. Regenerated amine is circulated back to the absorber.

The components of an amine gas treating plant include the contactor tower, flash tank, cross exchanger, particulate filter, charcoal filter, reboiler still column, reboiler, overhead condenser, condensate accumulator, reflux pump, booster pump, air cooler and injection pump.

ETI provides treatment systems to process and remove acid gases, hydrogen sulfide, and/or carbon dioxide from natural gas. The ETI process equipment scope of supply consists of both standalone vessels and skid-mounted modules and ETI can supply complete Amine Units or parts of the system depending upon the application and customer need.
