WATER-SOLUBLE ORGANIC MATERIAL CONDENSATION APPARATUS

摘要

A water−soluble organic material condensation apparatus equipped with a distillation column for distilling an aqueous solution of a water−soluble organic material,wherein a vapor generated at the top of the distillation column or a condensed liquid from the vapor is introduced to a device other than the distillation column which has the function to separate water from the water−soluble organic material to thereby condense the water−soluble organic material through separating water and then the condensed water−soluble organic material is recycled to the distillation column.The device other than the distillation column is desirably a separative film such as a zeolite film.The apparatus is improved in the operation of the upper portion of the condensation section of the distillation column and allows energy savings during distillation.
