FEEDSTOCK RECYCLING PROCESS FROM POLYESTER WASTES AND APPARATUS FOR USING THEREOF

摘要

An apparatus for regenerating the polyester waste, and a method for regenerating the polyester waste are provided to obtain dimethyl terephthalate and ethylene glycol with increasing reaction velocity and reducing the amount of required methanol. An apparatus for regenerating the polyester waste comprises a raw material supply hopper(10); a high pressure batch first reactor(100) where the glycolysis and methanolysis are carried out by using the raw material supplied from the raw material supply hopper; a condenser(40) which condenses the vapor material after the reaction of the first reactor is terminated; a low temperature continuous second reactor(200) which is connected with the first reactor and the transfer pipe(70a) and where the methanolysis is carried out by using the product of the first reactor; and a methanol storage bath(30) which supplies methanol to the first reactor and the second reactor.
