TOKYO, JAPAN: Sumitomo Chemical said that it has signed an agreement with S-Oil Corp of South Korea to license its polypropylene (PP) and propylene oxide (PO) manufacturing technologies to the oil refining company.
S-Oil operates a refinery complex with 669 kBPD (kilo barrel per day) of crude processing capacity in Ulsan, Korea and mainly produces fuel, lube base oil and petrochemical products.
In September this year, S-Oil has made the final investment decision on Residue Upgrading Complex and Olefin Downstream Complex Project of constructing 76 kBPD high-severity RFCC plant that upgrades low value residue oil to high value gasoline and propylene, and 405 KTA PP plant and 300 KTA PO plant that convert the propylene to the downstream products with target completion in the 1st half of 2018.
Sumitomo Chemical’s PP production technology has a proven track record of successful operations at various locations in the world, offering high quality products and maintaining stable plant operation over a period of time.
The PO technology is based on a PO-only process where PO alone is manufactured without accompanying co-products by recycling cumene. The cumene method, which was commercialized by Sumitomo Chemical for the first time in the world, has a distinct advantage of achieving a high PO yield by the combined use of the company’s proprietary high-performance epoxidation catalyst as well as ensuring superior stability in plant operation, it said.
