HEAT EXCHANGER AND PROCESS FOR DEVOLATILIZING POLYMERS USING SAME

摘要

Disclosed is a process for devolatilizing a polymer comprising the polymer through a devolatizer comprising a plate heat exchanger wherein the plate heat exchanger are heated by a plurality of heating tubes and wherein the heating tube comprises a return tube nested inside of a supply tube. The use of the disclosed invention allows for a comparatively small heat profile across heating plates as compared to prior art plate heat exchangers.
