Description
Summary:Polypropylene has become a major part of the modern plastics-resin market because of its unique physical properties, and is now employed in a wide range of applications from food packaging to automotive plastics. Historically, polypropylene has been produced at industrial scale by three main polymerization approaches: hydrocarbon slurry or suspension processes, bulk-phase processes and gas-phase processes. Propylene conversion to polypropylene is achieved through the use of a Ziegler-Natta catalyst. This process occurs in a continuous vertical stirred reactor at mild temperatures (about 80 degrees C). The process can be divided in three main areas: purification and reaction, resin degassing and pelletizing, and vent recovery.
