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. Vacuum treatment degasses and dehydrates industrial oil. This method is well suited for removing dispersed and dissolved water, as well as dissolved gases ...

There are several type of distillation: simple distillation, steam distillation etc. Water purification combines a number of methods to produce potable or drinking water.
centrifugation - separates oil into layers (an oil layer, a rag layer, a water layer,) by centrifugal forces; [4] filtration - separates suspensions into clean liquid and wet sediment with the help of filters; [5] Washing with water and dry washing to remove acidic products from oil (water-soluble low-molecular acids, salts of organic acids).
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.

A typical solid phase extraction involves five basic steps. First, the cartridge is equilibrated with a non-polar or slightly polar solvent, which wets the surface and penetrates the bonded phase. Then water, or buffer of the same composition as the sample, is typically washed through the column to wet the silica surface.
The Department of Labor is proposing to phase out a controversial Depression-era program that lets some employers pay disabled workers less than the federal minimum wage. Federal law currently ...
Commercial dubbin contains petroleum jelly (petrolatum), paraffin wax, neatsfoot oil, and naphtha (C10-12 alkane/cycloalkane). [2] More traditional dubbin can be made with beeswax, fish oil and lard. [3] The name dubbin is a contraction of the gerund dubbing, describing the action of applying the wax to leather. [4]
