Acid Gas:
What is Acid Gas:
Acid gas is a type of natural gas or any other gas mixture that contains significant quantities of hydrogen sulfide, carbon dioxide, sulfur oxides, nitrogen oxides, hydrogen halides, or similar acidic gases. Acid gases form acidic solutions when dissolved in water. Before a raw natural gas containing hydrogen sulfide or carbon dioxide can be used, the gas must be treated to reduce impurities to acceptable levels. This is commonly done with amine gas t...
