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...

Working of Crude Oil Distillation Column
The crude distillation unit (CDU) is the first processing unit in an oil refinery. In CDU main equipment is the crude oil fractional distillation column that separates the crude oil...

Crude Oil Assay
What is crude oil assay analysis? The crude oil assay is the collection of the results of physical tests that are performed to determine the key properties (boiling point, density,...

Types of Trays in Distillation Columns
Distillation is the most widely used separation process in oil refineries and chemical process industries. It is normally used to separate a mixture of materials to obtain one or more...

Catalytic Naphtha Reforming Process
Catalytic reforming is the chemical process in oil refineries for converting the low-value heavy naphtha fraction of crude oil into high octane reformate, aromatics rich feed-stock and hydrogen. High octane...

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.)...

Vacuum Distillation Unit in Oil Refinery
The vacuum distillation unit is designed to process the reduced crude from the atmospheric crude distillation tower bottom in the presence of vacuum. The VDU separates the reduced crude into...

Upgrading the Bottom of the Barrel
Oil refinery residue upgrading or bottom-of-the-barrel upgrading is the process of conversion of heavy petroleum fractions into high-valued lighter petroleum products. In oil refinery the term bottom of the barrel...

Isomerization Process in Oil Refinery
The Isomerization process in a petroleum refinery is the catalytic process that converts low octane number straight-chain hydrocarbon molecules (C4, C5, C6) into branched-chain hydrocarbons with the same carbon number...

Regeneration of Hydrotreating Catalysts
Regeneration is the process of restoring the activity of the catalyst by removing coke from its surface. It also involves the recovery of the physical properties of the catalyst. Regeneration...
