Acid gas is a particular typology of natural gas or any other gas mixture containing significant quantities of hydrogen sulfide (H₂S), carbon dioxide (CO₂), or similar acidic gases. The term/s acid gas and sour gas are often incorrectly treated as synonyms. Strictly speaking, a sour gas is any gas that specifically contains hydrogen sulfide in significant amounts; an acid gas is any gas that contains significant amounts of acidic gases such as carbon dioxide (CO₂) or hydrogen sulfide. Thus, carbon dioxide by itself is an acid gas but not a sour gas.
