Petroleum refinery in Anacortes, Washington, United States. Petroleum refining processes are the chemical engineering processes and other facilities used in petroleum refineries (also referred to as oil refineries) to transform crude oil into useful products such as liquefied petroleum gas (LPG), gasoline or petrol, kerosene, jet fuel, diesel oil and fuel oils.
In 1937, Sun Oil began operation of a new Houdry unit processing 12,000 barrels per day (1,900 m 3 /d) at their Marcus Hook refinery in Pennsylvania. The Houdry process at that time used reactors with a fixed bed of catalyst and was a semi-batch operation involving multiple reactors with some of the reactors in operation while other reactors ...
An oil refinery or petroleum refinery is an industrial process plant where petroleum (crude oil) is transformed and refined into products such as gasoline (petrol), diesel fuel, asphalt base, fuel oils, heating oil, kerosene, liquefied petroleum gas and petroleum naphtha.
There are three types of cokers used in oil refineries: delayed coker, fluid coker and flexicoker. [2] [3] The one that is by far the most commonly used is the delayed coker. The schematic flow diagram below depicts a typical delayed coker: A typical schematic flow diagram of a delayed coking unit
Refining of crude oils essentially consists of primary separation processes and secondary conversion processes. The petroleum refining process is the separation of the different hydrocarbons present in crude oil into useful fractions and the conversion of some of the hydrocarbons into products having higher quality performance.
Petroleum naphtha is an intermediate hydrocarbon liquid stream derived from the refining of crude oil [1] [2] [3] with CAS-no 64742-48-9. [4] It is most usually desulfurized and then catalytically reformed, which rearranges or restructures the hydrocarbon molecules in the naphtha as well as breaking some of the molecules into smaller molecules to produce a high-octane component of gasoline (or ...
Figure 2: Simplified animation of a typical dry vacuum distillation column as used in oil refineries Figure 3: Large-scale vacuum distillation tower at the Fawley oil refinery [9] Industrial-scale vacuum distillation [10] has several advantages. Close boiling mixtures may require many equilibrium stages to separate the key components.
A 4-drum delayed coking unit in a petroleum refinery. A delayed coker is a type of coker whose process consists of heating a residual oil feed to its thermal cracking temperature in a furnace with multiple parallel passes. This cracks the heavy, long chain hydrocarbon molecules of the residual oil into coker gas oil and petroleum coke. [1] [2] [3]
