Olefines production, Botany, at plant {AU}| | AusLCI, U
Unit process Australia v00.00.001
Included processes: production of ethylene from ethane feedstock via cracking process. Remark: Data is from the production of 1t of ethylene, based on data provided by Qenos for their Botany plant. The process involves cracking ethane from natural gas sourced from the Cooper Basin via the use of heat. The process includes the following steps: steam cracker, quench tower, gas compressor, treating, chilling train and fractionation. Allocation based on value of output. Geography: Refers to the production of Qenos' Botany 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
