Propylene Production from Ethylene - Cost Analysis - Propylene E21A

Book excerpt: This report presents a cost analysis of Polymer Grade (PG) Propylene production from ethylene using two integrated processes: dimerization and metathesis The processes examined are similar to CB&I Lummus technologies: Ethylene Dimerization Technology and Olefins Conversion Technology (OCT). In these processes, ethylene is first dimerized into butenes, and then, Propylene is produced through a metathesis reaction of 2-butene and ethylene. This report was developed based essentially on the following reference(s): (1) US Patent 8440874, issued to Lummus Technology and BASF in 2013 (2) US Patent 4242531, issued to Phillips Petroleum Company in 1980 Keywords: PG Propylene, Olefins Dimerization, Olefins Disproportionation, Lummus OCT, Olefins Metathesis, Phillips Triolefin, Propene, Ethene, On-Purpose Propylene Production
