Abstract

PURPOSE: To produce a medium to low density ethylene copolymer economically in good operability, by cooling a gas stream from a polymerization vessel fed with spent B-B and ethylene, discharging part of the resulting liquid portion out of the system and recirculating the gas portion to the vessel.
CONSTITUTION: Use is made of a C4 hydrocarbon mixture (spent B-B) obtained by removing butadiene from a C4 hydrocarbon fraction (B-B fraction) obtained, for example, by cracking naphtha. Into a polymerization vessel 5, e.g., stirred bed vapor-phase polymerization vessel, are fed ethylene 1, hydrogen 2, spent B-B 3 and catalyst components 4, 4', and reacted in a vapor phase, and the ethylene copolymer obtained is withdrawn from a pipe 6. On the other hand, a gas stream passed from the vessel 5 through a pipe 7 is cooled to a temperature at which the spent B-B liquefies, and separated in a condensation separation drum 12 into a gas portion and a liquid portion. The gas portion is circulated to the vessel 5 through a pipe 1, a blower 13 and a heater 14, and the major portion of the liquid portion is discharged through a pipe 9 out of the system. Part of the liquid portion is recirculated to the vessel 5 through a pipe 10.
