The image below is a schematic flow diagram of a typical petroleum refinery that depicts the various refining processes and the flow of intermediate product streams that occurs between the inlet crude oil feedstock and the final end-products. The diagram depicts only one of the literally hundreds of different oil refinery configurations.
The image below is a schematic flow diagram of a typical oil refinery depicting various unit processes and the flow of intermediate products between the inlet crude oil feedstock and the final products. The diagram depicts only one of the hundreds of different configurations.
A typical fluid catalytic cracking unit in a petroleum refinery. Fluid catalytic cracking (FCC) is the conversion process used in petroleum refineries to convert the high-boiling point, high-molecular weight hydrocarbon fractions of petroleum (crude oils) into gasoline, alkene gases, and other petroleum products.
The process flow diagram below depicts a typical semi-regenerative catalytic reforming unit. Schematic diagram of a typical semi-regenerative catalytic reformer unit in a petroleum refinery. The liquid feed (at the bottom left in the diagram) is pumped up to the reaction pressure (5–45 atm) and is joined by a stream of hydrogen-rich recycle gas.

The hot crude oil is then passed into a distillation column that allows the separation of the crude oil into different fractions depending on the difference in volatility. The pressure at the top is maintained at 1.2–1.5 atm [ 2 ] so that the distillation can be carried out at close to atmospheric pressure, and therefore it is known as the ...
The image below is a schematic depiction of the equipment and the process flow streams in a typical refinery HDS unit. Schematic diagram of a typical hydrodesulfurization (HDS) unit in a petroleum refinery. The liquid feed (at the bottom left in the diagram) is pumped up to the required elevated pressure and is joined by a stream of hydrogen ...
A coker or coker unit is an oil refinery processing unit that converts the residual oil from the vacuum distillation column into low molecular weight hydrocarbon gases, naphtha, light and heavy gas oils, and petroleum coke. The process thermally cracks the long chain hydrocarbon molecules in the residual oil feed into shorter chain molecules ...
