DISTILLATION TOWER SYSTEM AND METHOD FOR DISTILLING VINYLIDENE CHLORIDE MONOMERS USING SAME

摘要

The purpose of the present invention is to provide a distillation tower system and a method for distilling vinylidene chloride monomers using the same that can efficiently increase the yield rate for high-purity monomers. This distillation tower system (1) is a distillation tower system for purifying crude monomers after monomer synthesis, wherein the system comprises a first distillation tower (10) which is supplied with crude monomers, separates low-boiling-point components from a tower top section (10a), and collects from a tower base section (10b) crude monomers the low-boiling-point components of which have been removed; a second distillation tower (20) which is supplied with the crude monomers the low-boiling-point components of which have been removed, collects purified monomers from a tower top section (20a), and collects high boilers from a tower base section (20b); and a third distillation tower (30) which is supplied with the high boilers, collects the purified monomers from a tower top section (30a), and separates distillation residue from a tower base section (30b).
