Crude Oil Desalting Process
The crude oil desalting process extracts salts from a crude oil hydrocarbon stream by mixing the stream with a small amount of freshwater forming a water-in-oil emulsion. The resulting emulsion...

Hydrocracking Process in Oil Refinery
Catalytic cracking of heavy hydrocarbons in the presence of hydrogen is known as hydrocracking. The hydrocracking process converts heavy, high boiling petroleum feedstock into lighter products (naphtha, kerosene, diesel, etc.)...
