Research progress of waste gas treatment scheme in polyester plant
PBAT polyester has been widely concerned and applied because of its excellent degradability.In the process of producing PBAT polyester,it is inevitable to produce process waste gas.Therefore,this paper focuses on the main treatment schemes of PBAT process waste gas at present,including combustion method,low temperature water absorption method,adsorption method,biological method,membrane separation method and cryogenic tech-nology.The treatment methods are introduced and compared,and the future treatment technologies of PBAT waste gas are prospected.
