PROCESS AND APPARATUS FOR SEPARATING DILUENT FROM POLYMER SOLIDS

Application 392/CHENP/2005 published 2007-03-30, filed 2005-03-15
Polymer solids are maintained in an intermediate pressure zone for a desired polymer solids residence time and then transferred to a purge zone or other lower pressure zone. An increase in the polymer solids residence time in the intermediate pressure zone allows more diluent to flash or separate, thereby avoiding or reducing the need for a low pressure flash zone. A fluff chamber may be disposed between the intermediate pressure zone and a lower pressure zone. transporter tank may be used to transport polymer solids after the intermediate pressure zone.
