ABSTRACT:
This invention relates to a distillation column for removing vinyl chloride monomer or other volatile material from an emulsion, suspension or dispersion containing such material. The apparatus comprises a column in which a series of inverted cones are mounted. The dispersion or emulsion is pulled downwardly over the cones and steam is fed into the column through sparges and flows upwardly against the descending stream of material. The low boiling materials are distilled out and recovered for reuse. The stripped emulsion or dispersion are collected at the bottom of the column.
