Oil & Gas sweetening

Natural Gas often contain carbon dioxide (CO2), hydrogen sulfide (H2S) and other sulfur compounds which may require removal if their concetrations are above the acceptable limit. Carbon dioxide and hydrogen sulfide are known as acid gases because in the presence of water they form carbonic acid and sulfuric acid, respectively. When H2S and other sulfur compounds concentrations in the natural gas exceed acceptable limits, the natural gas is considered to be a “sour gas” and requires removal. The process of removing the H2S and other sulfur compounds is known as gas sweetening.

The key factors for gas sweetening are:

• Meet Sulfur Content Regulations

• Corrosion Prevention

• Increases The Heating Value Of The Natural Gas

• H2s Can Be Lethal In Small Quantities
