finishing process for distillate fuels (or vgo).

摘要

according to the invention.the proposed process is the treatment of distillate oil or vacuum coating (vgo) obtained from oil refineries by vacuum distillation of the residue).the after - flavouring and dewaxing distillate are oxidized at a temperature of 120 c and 180 c,then the distillates are chemical treatment with a mineral or a mixture of mineral base. the base reacts with the impurities contained in the gas.the mixture then passes through a thin film evaporator coupled with a balloon or an evaporator condensate, wet layer.the reaction products with mineral bases and the resulting polymers of the oxidation reaction are concentrated in the residue are separated by the bottom of the evaporator.the cutting oil is evaporated in the evaporator and condensed back into the ball and then cooled and sent to storage.the distillates obtained by vacuum distillation of the waste oil can be treated in the same way as the distillates of crude oil.
