High density polyethylene, slurry polymerisation 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 Resins plant in Altona. The process involves using Qenos' slurry polymerisation process to make high density polyethylene resin. The polymerisation reaction takes place in a saturated hydrocarbon solvent filled reactor. Following the polymerisation, the solvent is removed and recovered for reuse; the polyethylene powder then goes through a number of drying stages. The powder is then stored in silos before being processed through compounding, where raw polyethylene powder is processed together with additives. 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
