What is the overhead of the Amine stripper known as?

The overhead of the Amine stripper is known as Acid Gas because the stripping process focuses on removing hydrogen sulfide (H2S) and carbon dioxide (CO2) from the amine solution. During this process, these gases, which are acidic in nature, are released as a separate stream that can be referred to as Acid Gas. This stream is critical for further processing or disposal, as it contains significant amounts of the corrosive components that need to be handled safely in refining operations.

The other terms do not accurately describe the product of the Amine stripper. Sour Water Gas typically refers to gases dissolved in sour water, while Stripped Water would imply a cleared or treated water stream, which does not fit the context of gas separation. Amine Gas could be misleading, as it might imply the gas is primarily composed of amines instead of the target acid gases. Thus, Acid Gas is the appropriate and technically accurate term for the overhead from an Amine stripper.
