Fuel Oil Blending Process in Oil Refinery
Residual fuel oil is the third most important petroleum product after gasoline and diesel. Mostly, the furnace oils or bunker fuel oil are the by-products of refineries, which are blended...
-
Diesel Oil Blending Process in Oil Refinery
Commercial diesel fuel is a blend of many refinery streams. Blending components of diesel product may come from straight run diesel and kerosene from the crude distillation column, desulfurized diesel...

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
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...
-
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...
