desulfurization process of crude oil
As a critical function in refining, the crude oil desulfurization process significantly reduces the sulfur content of crude oil. The process helps to clean up the environment by cutting back on sulfur oxides, a major class of pollution. Technological aspects of the operation include the use of hydrodesulfurization units, which apply hydrogen under high pressure and temperature with a catalyst to convert sulfur compounds into hydrogen sulfide. Desulfurization applications are multiple, from environmental regulations to cleaner burning fuel production, thus improving overall sustainability for the oil industry.
