Extraction in chemistry is a separation process consisting of the separation of a substance from a matrix. The distribution of a solute between two phases is an equilibrium condition described by partition theory. This is based on exactly how the analyte moves from the initial solvent into the extracting solvent.
Giant fractionating column of Arak Oil Refinery manufactured by Machine Sazi Arak (MSA) A fractionating column or fractional column is equipment used in the distillation of liquid mixtures to separate the mixture into its component parts, or fractions, based on their differences in volatility. Fractionating columns are used in small-scale ...
Winterization of oil is a process that uses a solvent and cold temperatures to separate lipids and other desired oil compounds from waxes.Winterization is a type of fractionation (also known as fractionate crystallization), the general process of separating the triglycerides found in fats and oils, using the difference in their melting points, solubility, and volatility.
Specific microwave effects are those effects that cannot be (easily) emulated through conventional heating methods. Examples include: (i) selective heating of specific reaction components, (ii) rapid heating rates and temperature gradients, (iii) the elimination of wall effects, and (iv) the superheating of solvents. Microwave-specific effects ...
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.
For applications requiring only separation of a pre-mixed dispersion (e.g. oil/water separation in environmental cleanup), the direct feed offers the option to feed the mixed liquid stream at a low sheer force directly into the rotor. Inside the rotor, the liquids will be separated into a heavy (blue) and a light (yellow) phase.
The decanter centrifuge cannot separate biological solids with very small density differences, such as cells and viruses. [5] A competitive process that is capable of separating these difficult-to-separate solids is the tubular-bowl centrifuge. The machine can be very noisy and can cause vibration.
The primary goal of oil filtration is to enhance the oil’s performance, thereby protecting the machinery and extending its service life. [ 3 ] Filtration is also used to describe biological and physical systems that not only separate solids from a fluid stream but also remove chemical species and biological organisms by entrainment ...
