- 1 - Title of the Invention: MONOMERIC VINYL CHLORIDE STRIPPING TOWER Abstract of the Disclosure: Disclosed herein is a stripping tower adapted to remove unreacted vinyl chloride from a suspension or emulsion of a vinyl chloride resin after its polymerization reaction. The tower is a packed tower filled with a packing such as Tellerette packing. A condenser is provided in direct attachment to a top portion of the packed tower so that steam, which is discharged together with stripped monomeric vinyl chloride gas, is condensed in the condenser, separated from the monomeric vinyl chloride gas and then recirculated to the packed tower. Use of a packed tower as a stripping tower and steam as a stripping medium enjoys good removal efficiency of monomeric vinyl chloride but is accompanied by occurrence of a large volume of foams of a polyvinyl chloride slurry in the tower. Foams of the slurry eventually overflow from the top of the tower and do not permit any further continuation of the operation. Provision of the condenser in direct attachment to the top portion of the tower was found to be effective in suppressing the occurrence of foams, thereby permitting efficient removal of monomeric vinyl chloride.
