Capacity: 120,000 TPY HDPE Plant Description: High Density Polyethylene Manufacturing Facility, “HDPE” 120,000 ton per year. Introduction: This plant was built in the vicinity of “OMV” oil refinery which supplies the feed stock to the plant. The “OMV” refinery has a cracker unit which provides the gaseous Ethylene required for the production of Polyethylene at the HDPE plant... The “HDPE” plant has the “Univation’ technology for the production of Polyolefin at this location. Plant was designed and built on 1986 and shut down in 2005. HDPE Plant Process Description: ------------------------------------------------------ The plant was originally designed and built on 1986 for a capacity of 80,000 metric ton per year of High Density Polyethylene, “HDPE”. The capacity has been raised to 120, 000 ton per year only by optimizing the process conditions rather than adding equipment or upgrading the reactor. Presently plant is operating at 110,000 ton per year capacity in line with the demand in that area. The Major operating Areas of the production unit consist of: - Feed gas Purification Section - Compression and Reaction/ Reactor - Purge bins and vent recovery - Extruder and packaging system (The packaging section will not be available with the plant). The extruder is part of the plant. The Process Description: 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 a powder state and 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 Bagging and packaging system .
