desulphurization of petroleum
The removal of sulfur from petroleum distillate is an important step in refining the sulphur dioxide contained in crude oils and their products. Its primary purpose is to reduce the sulfur levels to meet environmental standards and to improve fuel quality. Technological aspects of desulfurization include the use of catalysts, hydrotreating techniques, and-absorption techniques that simply scrub the sulfur right out of hydrocarbons. Professional usage goes from making clean(er) gasoline or diesel fuel right up to bringing environmental bites to bear in petrochemical plants. This procedure is indispensable for decreasing air pollutants and preventing the risks of sulfur dioxide emitted into the atmosphere.
