Modeling Polymer Recovery
In this simulation you will model a simplified polymer washing and drying process.
You will use:
•Component attribute GENANAL to characterize a nonconventional (NC) component
•The hydrocyclone model (HyCyc)
•The counter-current decanter model (CCD)
•The cyclone model (Cyclone)
Allow about 30 minutes to do this simulation.

Polymer Recovery Flowsheet
The process flow diagram and operating conditions for this simulation are shown in the following figure.
The feed stream FEED, a dilute slurry of polymer in acetone, is concentrated in a hydrocyclone. The concentrated slurry of polymer in acetone is then washed with water in a countercurrent decanter. The resulting slurry of polymer in water is dried with nitrogen. The gases from drying are separated from the solid polymer in a cyclone.
