Abstract

PURPOSE: To distill two or more kinds of stock oils by a plant, separately, in high efficiency, by heating the stock oils, introducing to the bottom part of respective distillation columns, distilling in the flashing zone of the columns, collecting the distillates of the columns, and again distilling the collected mixture in a distillation column.
CONSTITUTION: Different kinds of stock oils A and B are heated in heat-exchangers 8 and 9 and a furnace 3, and introduced into distillation columns 1 and 2 from their bottoms to the flashing zones. Light fractions and heavy gas-oil fractions are removed by the small-sized column 2, and the vapor of the fractions containing kerosene and naphtha distilled from the top of the column 2 is introduced to the middle part of the column 1 through a pipe 6. The introducing position of the column 1 depends upon the composition of the distillate. Kerosene and naphtha are obtained from the column 1. High kerosene yield, and extremely high operation efficiency.
