Gaseous Phase Disengaging Apparatus

A gaseous phase disengaging apparatus for the liquid phase process material contaminated with a substance of lower boiling point consists of a twin screw extruder. The raw feed is passed through the twin screw extruder and the feed is repetitively spread over the apparatus inside surfaces. The apparatus is provided with paired raw material supply inlets and gaseous phase vent ports. These are maintained in continuous communication during screw rotation.
