What is a refinery amine unit?

Answer 1

A refinery amine unit is a part of a petroleum refinery that utilizes amine solvents to remove acidic gases, such as hydrogen sulfide (H₂S) and carbon dioxide (CO₂), from natural gas and other refinery streams. The process typically involves contacting the gas with the amine solution, which selectively absorbs the acidic components. After absorption, the amine solution is regenerated through heating, releasing the captured gases and allowing the amine to be reused. This unit is essential for producing cleaner fuels and meeting environmental regulations.
