Oil refineries

industrial process plant where crude oil is processed and refined into more useful products

thumb|The Alpena biorefinery plant in the USA A biorefinery is a refinery that converts biomass to energy and other beneficial byproducts (such as chemicals). The International Energy Agency Bioenergy Task 42 defined biorefining as "the sustainable processing of biomass into a spectrum of bio-based products (food, feed, chemicals, materials) and bioenergy (biofuels, power and/or heat)". As refineries, biorefineries can provide multiple chemicals by fractioning an initial raw material (biomass) into multiple intermediates (carbohydrates, proteins, triglycerides) that can be further converted in

A device used in several industrial applications to separate a vapor–liquid mixture.

A desalter is a process unit in an oil refinery that removes salt from the crude oil. The salt is dissolved in the water in the crude oil, not in the crude oil itself. The desalting is usually the first process in crude oil refining. The salt content after the desalter is usually measured in PTB – pounds of salt per thousand barrels of crude oil. Another specification is Basic sediment and water.

Industrial wastewater processing device

A visbreaker is a processing unit in an oil refinery whose purpose is to minimize the quantity of residual oil produced in the distillation of crude oil and to increase the yield of more valuable middle distillates (heating oil and diesel) by the refinery. A visbreaker thermally cracks large hydrocarbon molecules in the oil by heating in a furnace to lower its viscosity and to produce small quantities of light hydrocarbons. (LPG and gasoline). The process name of "visbreaker" refers to the fact that the process lowers (i.e., breaks) the viscosity of the residual oil. The process is non-catalyt
