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.
Mechanical processes, including solids transportation, crushing and pulverization, and screening and sieving. Chemical engineering unit operations also fall in the following categories which involve elements from more than one class: Combination ; Separation (distillation, crystallization) Reaction (chemical reaction)
Industrial separation processes are technical procedures which are used in industry to separate a product from impurities or other products. The original mixture may either be a natural resource (like ore , oil or sugar cane) or the product of a chemical reaction (like a drug or an organic solvent ).
To control the separation process, the operational parameters should be transferred from the rotating part to the stationary part of the decanter whilst also constantly controlling and maintaining the mechanical device inside the process region. This can be achieved using hydraulic and electronic transfer systems.
Membrane separation processes operate without heating and therefore use less energy than conventional thermal separation processes such as distillation, sublimation or crystallization. The separation process is purely physical and both fractions ( permeate and retentate ) can be obtained as useful products.
As described above, the mix & separation configuration is the standard operation for centrifugal contactors used for liquid-liquid extraction processes. The two liquids (typically an aqueous phase (heavy) and an organic phase (light)) enter the annular mixing zone where a liquid-liquid dispersion is formed and extraction occurs as solutes (e.g ...
Mixer-settler scheme. Mixer settlers are a class of mineral process equipment used in the solvent extraction process. A mixer settler consists of a first stage that mixes the phases together followed by a quiescent settling stage that allows the phases to separate by gravity.
VSA typically draws the gas through the separation process with a vacuum. For oxygen and nitrogen VSA systems, the vacuum is typically generated by a blower. Hybrid vacuum pressure swing adsorption (VPSA) systems also exist. VPSA systems apply pressurized gas to the separation process and also apply a vacuum to the purge gas.
