Abstract: An apparatus for separating dimethylterephthalate from polyester methanolysis gas is provided to simplify a partial condenser and a spray tower or spray zone, and to save energy by using the heat of methanolysis gas as distillation energy. An apparatus for separating dimethylterephthalate from methanolysis gas comprising dimethylterephthalate, methyl-2-hydroxyethylterephthalate, ethyleneglycol, and methanol as depolymerization products of polyethyleneterephthalate includes: a liquid storage tank(10) in which an inflow of methanolysis gas is condensed; a methanol distillation column(20) provided in the upper part of the liquid storage tank; an ethyleneglycol distillation column(30) provided in the lower part of the liquid storage tank; and a dimethylterephthalate storage tank(40) provided in the lower part of the ethyleneglycol distillation column.

Abstract: 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.
