Abstract

PURPOSE: To recover the unreacted vinyl chloride monomer from an aqueous dispersion of vinyl chloride homo- or copolymer, efficiently, in a short time, using a simple equipment, by spraying the dispersion horizontally or upward in a degassing tube to vaporize the unreacted monomer, and separating the monomer vapor from the polymer slurry with a separator.
CONSTITUTION: A polymer slurry in a polymerizer 1 is sprayed by the internal pressure of the polymerizer and with a pump 5 through a valve 6 into a degassing tube 2 which is heated with a jacket 3. The tube 2 has a length/diameter ratio of 10W200, and the spraying is pref. carried out at a linear velocity of 10W30m/sec, a residence time of 0.05W10 seconds, and a pressure difference of 2W10kg/cm2. The unreacted monomer vaporized in the tube 2 is transferred together with the polymer slurry to a separator 8 such as cyclone, and separated from the slurry. The monomer is stored in a gas holder 10, and the slurry is sent through an intermediate tank 11, a pump 12, and stored in a slurry tank 13.
