High density polyethylene, gas phase process, at plant {AU}| | AusLCI, U
Unit process Australia v00.00.001
Included processes: production of high density polyethylene from ethylene feedstock Remark: Data is for the production of 1t of HDPE, based on data provided by Qenos specific to the Qenos Plastics plant in Altona. The process involves using Qenos' low pressure Unipol gas phase process to make high density polyethylene resin. This process uses transition metal catalysts to initiate the polymerisation process, which enable the reaction to occur at 2000 kPa / 100C. Geography: Refers to the production of Qenos' Altona plant Technology: Average Time period: Data collected for 2013/2014 Version 1.0 Record: Data entry by: Paul-Antoine Bontinck E-mail: paul@lifecycles.com.au; Company: LCS; Country: AU Generator: Generator/publicator: Tim Grant Telephone: 0061 408104977; E-mail: tim@lifecycles.com.au; Company: LCS; Country: AU
