FIELD: oil and gas production.
SUBSTANCE: invention refers to procedure of clarification of oil distillate under effect of magnetic field consisting in clarification of oil distillate with N-methyl-pyrrolidone, also, oil distillate is subjected to effect of constant magnetic field with induction 0.05-0.25 tesla. Force lines of constant magnetic field are directed perpendicular to vector of flow of oil distillate, while linear rate of flow in an active gap of a magnetizator amounts to 0.01-03 m/sec, whereupon oil distillate is mixed with N-methyl-pyrrolidone.
EFFECT: improved quantitative and qualitative indices of finish product, reduced critical temperature of oil distillate dissolving in N-methyl-pyrrolidone and reduced temperature of extraction.
