Exergy study of amine regeneration unit using diethanolamine in a refinery plant: A real start-up plant [PDF]
Heliyon, 2021 Refinery plants use diethanolamine (DEA) solutions for gas sweetening. The role of DEA is to absorb H2S from sour gas. Amine Regeneration Units (ARU) are used to regenerate the rich Amine with H2S from refinery units to Lean Amine.
