Exergy study of amine regeneration unit for diethanolamine used in refining gas sweetening: A real start-up plant

Alexandria Engineering Journal, 2022
Diethanolamine (DEA) solutions are used in refineries to sweeten gas. DEA is responsible for absorbing H2S from sour gas. In an Amine Regeneration Unit (ARU), the rich amine with H2S is regenerated. A refining column in the Middle East started commercial
