Definition - What does Desulphurization mean?
Desulfurization refers to the industrial process of removing sulfur from a mineral resource mixture such as crude oil. It predominantly involves a gas-purification industrial procedure used to remove hydrogen sulfide (H2S) and carbon dioxide (CO2) from a given mineral resource.
Desulphurization may also be known as gas sweetening or amine gas treating.
Corrosionpedia explains Desulphurization
Crude oil with a higher concentration of hydrogen sulfide is referred to as sour, while crude oil with a lower concentration of hydrogen sulfide is referred to as sweet. The acid gas removal involves the use of aqueous solutions (amines) to react with the existing mixture. This process is vital as hydrogen sulfide promotes corrosion of any metal vessel it is housed or transported in. Hydrogen sulfide is also extremely toxic and harmful to humans and the environment.
