摘要
PROBLEM TO BE SOLVED: To provide an apparatus and method for distilling volatile organic compounds which saves space and energy and stabilizes operation.;SOLUTION: In the distillation method for volatile organic compounds which recovers the volatile organic compounds from exhaust air containing the volatile organic compounds and refines the recovered volatile organic compounds, when water is removed from the recovered volatile organic compounds to extract the volatile organic compounds and high volatile compounds in a first distillation column and the high volatile compounds are removed from the extract to extract refined volatile organic compounds in a second distillation column, steam is supplied from a common reboiler to distillate the volatile organic compounds in the first and second distillation columns, steam obtained by the distillation is condensed in a common condenser, a condensate from the condenser is separated into a volatile organic compound phase and an aqueous phase, and the separated volatile organic compounds are returned from the tops of the first and second distillation columns by the approximately same amount.;COPYRIGHT: (C)2012,JPO&INPIT
