Hydrotreating

UREA

About

Hydrotreating process is very important for quality oil refining. Motor fuels are hydrotreated to remove sulfur, metals, nitrogen and other heteroatomic compounds from their composition, thus reducing the corrosiveness of fuels, their tendency to precipitate and the amount of gas emissions. Hydrotreating of gasoline fractions is carried out to protect reforming catalysts from poisoning by non-hydrocarbon compounds. The catalytic cracking feedstock, vacuum gasoil, is hydrotreated to increase the yield of cracking products. Hydrotreating petroleum oils improves their performance characteristics
