Ethylene-vinyl acetate copolymer production plant, the production process is: added vinyl acetate, initiator, molecular weight regulator as well as ethylene which is compressed twice by JI01 and JI02 into tubular reactor D101, polymerized at temperature of 2O5~2IO °C and pressure of 140 ~ 145 MPa, obtained crude product containing vinyl acetate copolymer. Firstly, separated the crude product and the unreacted gas at 22-25 MPa in high pressure separator L101, re-reacted the unreacted gas by high pressure circulating chiller C101. Vinyl acetate, separated from high pressure separator L101, re-enters the reaction via a low pressure cycle system. Separated the polymer from low pressure separator LI02, extruded, pelletized, dried and obtained the product. The advantages of this invention are that the reaction time is reduced and the reaction rate is improved.
