2. Coker unit - Wikipedia

   en.wikipedia.org/wiki/Coker_unit

   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.

3. Delayed coker - Wikipedia

   en.wikipedia.org/wiki/Delayed_coker

   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.

4. Visbreaker - Wikipedia

   en.wikipedia.org/wiki/Visbreaker

   A schematic diagram of a Visbreaker unit. The term coil (or furnace) visbreaking is applied to units where the cracking process occurs in the furnace tubes (or "coils")."). Material exiting the furnace is quenched to halt the cracking reactions: frequently this is achieved by heat exchange with the virgin material being fed to the furnace, which in turn is a good energy efficiency step, but ...

5. Petroleum refining processes - Wikipedia

   en.wikipedia.org/wiki/Petroleum_refining_processes

   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.

6. Atmospheric distillation of crude oil - Wikipedia

   en.wikipedia.org/wiki/Atmospheric_distillation...

   Crude oil exits from the desalter at a temperature of 250 °C–260 °C and is further heated by a tube-still heater to a temperature of 350 °C–360 °C. 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 .

7. Industrial furnace - Wikipedia

   en.wikipedia.org/wiki/Industrial_furnace

   An industrial furnace, also known as a direct heater or a direct fired heater, is a device used to provide heat for an industrial process, typically higher than 400 degrees Celsius. [1] They are used to provide heat for a process or can serve as reactor which provides heats of reaction. Furnace designs vary as to its function, heating duty ...

8. Oil refinery - Wikipedia

   en.wikipedia.org/wiki/Oil_refinery

   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.

9. Catalytic reforming - Wikipedia

   en.wikipedia.org/wiki/Catalytic_reforming

   Catalytic reforming requires a whole range of other processing units at the refinery (apart from the distillation tower, a naphtha hydrotreater, usually an isomerization unit to process light naphtha, an aromatics extraction unit, etc.) which puts it out of reach for smaller (micro-)refineries.
