摘要： PURPOSE: To make it possible to lower a tower bottom temp. and to perform energy conservation, in a distillation tower with a reboiler, by a method wherein steam obtained from the tower top is raised in pressure, cooled and condensed while a part thereof is returned to the tower top part of the distillation tower.
CONSTITUTION: Stock oil is supplied to a distillation tower 1 from a line 6 and heated by the reboiler provided to the lower part of a distillation tower. Steam is recovered from the tower top part of the distillation tower through a line 3 and, after compressed by a compressor 30, the compressed steam is cooled and condensed by a condenser 20 and a part thereof is refluxed to the tower top from a reflux drum 10 through a line 14 to perform rectification.
