Petroleum Refinery Processes

Blending of Petroleum Products

The physical process of mixing two or more petroleum products with different properties to produce a homogeneous finished product with desired characteristics is called blending in petroleum refinery. The main

Troubleshooting of Crude Oil Distillation Column

The crude oil feedstock is separated into valuable petroleum products in the Crude Distillation Unit (CDU). The crude oil distillation column is the key processing equipment that must be operated under

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

Catalytic Naphtha Reforming Process in Petroleum Refinery

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.) or

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 a vacuum. The Vacuum Distillation Unit separates the

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 an oil refinery, the term bottom of the

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
