The main drawback of this process is its longevity. [citation needed] Filtration is a partial removal of solid particles through filter medium. Oil filtration systems generally use a multistage filtration with coarse and fine filters. [2] Centrifugation is separation of oil and water, or oil and solid particles by centrifugal forces.
Bitumen froth treatment is a process used in the Athabasca oil sands (AOS) bitumen recovery operations to remove fine inorganics—water and mineral particles—from bitumen froth, by diluting the bitumen with a light hydrocarbon solvent—either naphthenic or paraffinic—to reduce the viscosity of the froth and to remove contaminants that were not removed in previous water-based gravity ...
Ion exchange is widely used in the food and beverage industry, hydrometallurgy, metals finishing, chemical, petrochemical, pharmaceutical technology, sugar and sweetener production, ground- and potable-water treatment, nuclear, softening, industrial water treatment, semiconductor, power, and many other industries.

Water purification combines a number of methods to produce potable or drinking water. Downstream processing refers to purification of chemicals, pharmaceuticals and food ingredients produced by fermentation or synthesized by plant and animal tissues, for example antibiotics, citric acid, vitamin E, and insulin.
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.
the reaction steps presented here are just a part of the reaction sequence, see reference for more details. Fenton based AOP: [16] Fe 2+ + H 2 O 2 → Fe 3+ + HO· + OH − (initiation of Fenton's reagent) Fe 3+ + H 2 O 2 → Fe 2+ + HOO· + H + (regeneration of Fe 2+ catalyst) H 2 O 2 → HO· + HOO· + H 2 O (Self scavenging and decomposition ...
A separation process is a method that converts a mixture or a solution of chemical substances into two or more distinct product mixtures, [1] a scientific process of separating two or more substances in order to obtain purity. At least one product mixture from the separation is enriched in one or more of the source mixture's constituents.
Brine treatment is commonly encountered when treating cooling tower blowdown, produced water from steam-assisted gravity drainage (SAGD), produced water from natural gas extraction such as coal seam gas, frac flowback water, acid mine or acid rock drainage, reverse osmosis reject, chlor-alkali wastewater, pulp and paper mill effluent, and waste ...
