Over the last few years, SRI Consulting has updated several polyethylene processes in
separate PEP reviews or reports. In the current review, the capital costs and production costs
of the different polyethylene processes are compared based on production of a similar product.
The processes compared are Univation’s UNIPOL™ gas-phase process, Basell’s Spherilene™
S gas-phase process, Chevron Phillip’s slurry loop process and Ineos Innovene™ G gasphase
process. The production costs are based on the production of a homopolymer HDPE.
