What is sour gas?

The term acid gas covers any type of gas or gaseous mixture, which when mixed with water forms an acidic compound. The most common types of sour gases are hydrogen sulphide (H _{2 2 ). The acid gases are found in natural gas and must be removed by a process known as an amino gas before natural gas usable. While the terms sour gas and sour gas are often used by mistake to describe acid gases, the terms are not the same. The acid gas contains a high amount of hydrogen sulfide, while the real sour gas contains one of the acid gases. However, carbon dioxide is acid gas but not technically sour gas. These acidic materials must remove the gases before use. This is achieved by the process of amino gas processing, referred to as matching. The process takes certain liquids and uses it to remove the harness of hydrogen sulphide and carbon dioxide or other combination of acid gases from natural gas.}

sweetening causes the hydrogen sulfide and carbon dioxide to separate from the natural gas. This is crucial, because as types of acid gas, these two substances become acidic when they get into contact with water. Any building gas pipeline will have problems from these acid gases if it is not removed. Acid starts eating pipes and causes leakage. The occurrence of these gases also limits the types of materials that can be used to install gas lines.

Ethanolamine is added to align natural gas using an amino gas processing process. Ethanolamine is a solvent that scrubs or cleans acid gases; It absorbs carbon dioxide and hydrogen sulphide, but leave the other gases untouched. There are several types of organic compounds of ethanolamine. Conventional compounds used in the matching process include monoethanolamine (Mea) and methylidiethanolamine (MDEA).

In addition to the risk of pipe damage is a highly toxic and dangerous, even deadly animals orpeople who are exposed to him. It is also flammable and produces a disgusting odor, and so where the name “sour gas” comes from. Carbon dioxide is not acid gas and, unlike hydrogen sulphide, is odorless gas.
