The Kian Petrochemical (Olefin 12) Project will be developed in two phases. Phase I includes the Olefin Plant and the High-Density Polyethylene (HDPE) Unit, while Phase II comprises the Oxo Alcohols, Propylene Oxide, and Styrene Monomer units. Feedstock for the complex, including ethane, propane, butane, C3+ and C5+, will be supplied from the South Pars Gas Refineries and other petrochemical facilities located in the South Pars Petrochemical Zone.
