Homopolymers, Copolymers, LLDPE grade ore possible

The Plant was originally designed and built in 1986 for a capacity of 100,000 MTPY of High Density Polythylene, "HDPE".  The reactor itself is oversized and has a much larger capacity.

The production has been increased to 120,000 TPY only by optimizing the process conditions rather than adding equipment or upgrading the reactor.

Plant was operating and running at 110,000 TPY capacity inn line with the demand in that area prior to shutdown.

The polymerization happens in the reactor over a catalyst of Zeolite at about 100° C and 290 psig.

The reaction is in the gas phase and the catalyst injection is in "powder state" and it is continuous injection.

The polyolefin molecules discharge from the bottom of the reactor in solid and powder state.  The process technology of gas phase reactor is very clean and easy to control.  The product flows from reactor down into the purge-bin, then to the storage bins where after adding additives and in case adding color, product flows to the extruder and ultimately to the bagging and packaging system.
