Abstract

Способ очистки экстрагентов, используемых в процессах разделения Cили Cуглеводородов экстрактивной ректификацией, от тяжелого остатка путем вакуумной перегонки с отбором в дистиллате очищенного экстрагента и в кубовом продукте - смеси экстрагента и тяжелого остатка, отличающийся тем, что, с целью снижения потерь экстрагентов и уменьшения коррозии оборудования, перегонку проводят в присутствии фосфорной кислоты при концентрации ее в кубовом продукте от 0,1 до 10% мас.The method of purification of extractants used in separation processes of Cili Hydrocarbons by extractive distillation from heavy residue by vacuum distillation with selection of purified extractant in distillate and in bottom product - mixture of extractant and heavy residue, in order to reduce the loss of extractants and reduce equipment corrosion , the distillation is carried out in the presence of phosphoric acid at a concentration in the bottom product from 0.1 to 10% wt.
