Изобретение относится к нефтеперерабатывающей промышленности, а именно к переработке нефтяных остаточных фракций вакуумной перегонкой. Цель изобретения - получение качественного остатка вакуумной колонны за счет уменьшения содержания в нем дизельных фракций. В качестве испаряющего агента при вакуумной перегонке мазута используют пары дизельного топлива, которые попадают в остаток колонны. Для отпаривания паров дизельного топлива остаток направляют в отдельный испаритель, при этом образовавшиеся пары подают в верхнюю часть вакуумной колонны.The invention relates to the refining industry, in particular to the processing of oil residual fractions by vacuum distillation. The purpose of the invention is to obtain a high-quality residue of the vacuum column by reducing the content of diesel fractions in it. As a vaporizing agent during vacuum distillation of fuel oil, diesel fuel vapors are used, which fall into the remainder of the column. For steaming diesel fuel vapor, the residue is sent to a separate evaporator, while the resulting vapor is fed to the top of the vacuum column.
