Gasoline in the refining process often contains contaminants which must be removed to meet market specifications, comply with emissions and regulatory standards, and control corrosion. Gas sweetening is the process of removing contaminants, mainly the acid gases hydrogen sulfide and carbon dioxide, which turns acid gases into sweet gases.

The Sweetening training course identifies and discusses gas sweetening. It explains the role amines and solvent have in the process. This online course also describes the process and equipment associated with a sweetening plant. It includes:

• Purpose of gas sweetening
• Major system components
• Amines and solvents

Sweetening is part of the Refinery Operations training series.
