Sweet Gas

Definition - What does Sweet Gas mean?

Sweet gas is natural gas that is found as a hydrogen sulfide. The gas may not contain any carbon dioxide. The composition of the gas determines whether it is sweet or sour. Sweet gas in its purest form can be used with very little refining. It is not corrosive in nature; hence it is relatively easy to use as compared to sour gas.

Petropedia explains Sweet Gas

Natural gas is extracted from gas wells, condensate wells and crude oil wells. The gas extracted from these wells is characterized based on its extraction from the type of the well. For example, non-associated gas is a form of natural gas that is extracted from condensate and gas wells. On the other hand, associated gas is a form of natural gas that is extracted from crude oil wells. When the extracted natural gas is found to be free from hydrogen sulfide, it is called sweet gas. Also known as sweet natural gas, it can be processed easily as it does not require a lengthy purifying process.

When natural gas contains high levels of acidic gases such as hydrogen sulfide, it is referred to as acid gas. If it contains high levels of sulfur, it is referred as sour gas.
