Резюме:

Hydrogen sulfide can be released as a result of both natural and anthropogenic activities. Anthropogenic causes generate H2S through the release of naturally occurring H2S from oil and natural gas processing; Other causes that emit this toxic gas include municipal waste disposal, biogas production and sewerage. Although important, H2S generation is not a major part of total natural sulfur dioxide emissions, which recycles into dimethyl sulfide and CO2. This gas occurs naturally in the oceans and also in other places such as other bodies of water, volcanoes, etc., as well as gas and oil fields. Due to human health and environmental concerns, numerous restrictions and regulations have been placed on gas sales specifications. The permissible concentration of H2S is 4 to 20 parts per million (ppm) and no more than 3% CO2. Therefore, acid gas must undergo a gas purification process, namely gas desulfurization. In the gas purification process, acid gases such as H2S and CO2 are removed to form sweet gas.

Keywords: acid gas, hydrogen sulfide, absorption, adsorption, desulfurization
