Abstract

PURPOSE:To carry out economical separation in an erergy conserving manner even in a system wherein the difference of b.p. of objective light and heavy components is higher than 20 deg.C, by a method wherein rectification due to vapor re-compression type heat recovery is carried out in the first tower and an intermediate heavy component is separated by a conventional method in the second tower. CONSTITUTION:A raw liquid 19 comprising a mixture of dimethylformamide (DMF) and water is continuously supplied to the feed part 4 of the first tower 1. After the vapor of the objective light component issued from the tower top part 5 is pressurized by a vapor compressor 7 and condensed to be introduced into a drum 9, a part thereof is refluxed to the tower top part 5 by a reflux pump 10 and the remainder is recovered as the objective light component 20. On the other hand, an objective heavy component 21 is recovered from the tower bottom part 16 of the second tower and a part of the condensed liquid from a condensor 17 is returned to the tower top part 15 as a reflux liquid 23 and the remainder is recovered as a distillate 22. By this method, a desired amount of heat in the second tower is reduced considerably as compared to a conventional method wherein a stock material is directly treated in a distillation tower.
