What is sour gas?

Acid gas is a term used to indicate gas that contains hydrogen sulphide at concentrations higher than four parts per million. The term 'sour gas' is usually used with a reference to natural gas, although it can also be used for discussion about other gases. Before safe use, it is necessary to treat gas with dirt, such as hydrogen sulphide. The gas refine process includes a step known as "matching" to remove hydrogen sulphide and other materials. These impurities must be removed in the refinery to ensure that the gas is done in a stable and predictable way when it is used. In the case of acid gas, the hydrogen sulphide gauge gives a significantly strong odor that makes it easier to identify and the harmonizing process removes a large part of the odor. Specialized pipes and equipment are needed to avoid side effects during transport, which could pose a security risk. Once acid gas arrives in refinery, it can be releaseda number of processes to sweeten it. Usually, hydrogen sulphide is not the only dirt in the gas, with acid gas often containing carbon dioxide.

The narrow term is "sour gas". Sour gas is a natural gas that has a high concentration of acid gases. It must also be processed before it can be used safely. However, acid gas and sour gas are not the same. This means that there are often a large part between acidic and acid gases, because impurities in natural gas supply are neatly limited to different areas.

Drillers and refiner devices can perform tests to learn about the composition of raw natural gas and determine the most suitable methods of gas treatment. During the refining process, the natural gas content is standardized to be used in any system for the use of natural gas for heat or energy. These systems are usually not designed to deal with the traceMi dirt, which is decisive for providing a consistent and reliable product to prevent damage to natural gas systems or represent a security risk to users of such systems.
