FIELD: oil and gas industry.
SUBSTANCE: polymer additive deparaffination of oil fractions comprises active component and solvent; copolymer of higher alkyl acrylates with linear alkyl groups C16-C20 and N,N-dymethylamino ethyl methacrylate are used as the active component while any fit solvent that ensures solubility of the additive in raw mix (benzene, toluene, oil, etc.) is used as the solvent with the following ratio of components, wt %: copolymer 54-57; solvent - the remaining share. The copolymer has number-average molecular weight of 17000-200000, it contains 90-95 mol % of links of higher alkyl acrylates and 5-10 mol % of links of N,N-dymethylamino ethyl methacrylate.
EFFECT: additive increases oil yield and speed of filtering process.
