CONDENSATION AND WASHING DEVICE, POLYMERISATION DEVICE AND METHOD FOR CLEANING PROCESS STEAM DURING THE PRODUCTION OF POLYLACTIDE

摘要

The present invention relates to a condensation and washing device with which in particular the process vapours which occur during the production of polylactide can be processed and cleaned. Furthermore, the present invention relates to a polymerisation device for the production of polylactide and also to a method for processing process vapours which occur during the production of polylactide; possibilities for use of both the condensation and washing devices and of the method are likewise mentioned.
