Linear low density polyethylene, at plant {AU}| | AusLCI, U
Unit process Australia v00.00.001
Included processes: production of linear low-density polyethylene from ethylene feedstock Remark: Data is for the production process resulting in the production of LLDPE, based on data provided by Qenos specific to the Qenos Alkatuff plant in Botany. The process involves using Qenos' low pressure Unipol gas phase process to produce LLDPE. 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' Botany plant Technology: Average Time period: Data collected for 2009/2010 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
