Sumitomo Chemical will license its technologies for manufacturing polypropylene (PP) and propylene oxide (PO) to S-Oil Corp. of South Korea.

S-Oil operates a refinery complex with 669 kilo barrel per day (KBPD) of crude processing capacity in Ulsan, Korea and mainly produces fuel, lube base oil and petrochemical products.

“In September this year, S-Oil took an investment decision on Residue Upgrading Complex and Olefin Downstream Complex Project by constructing a 76 KBPD high-severity RFCC plant,” a Sumitomo press release said.

The RFCC plant will upgrade low value residue oil to high value gasoline and propylene, while a new 405 KTA PP plant and 300 KTA PO plant will convert the propylene to downstream products.

“Sumitomo Chemical's PP production technology has a proven track record of successful operations at various locations in the world, such as the Company's Chiba Works in Japan and licensee companies,” it added.

Sumitomo's production 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 commercialised by Sumitomo Chemical for the first time in the world, has a distinct advantage of achieving a high PO yield,” Sumitomo observed.

This is achieved by the combined use of the Company's proprietary high-performance Epoxidation catalyst as well as ensuring superior stability in plant operation.

“The technology has successfully been in operation on a commercial scale at Sumitomo Chemical's Chiba Works and an affiliate in Saudi Arabia,” the company informed.

Sumitomo Chemical intends to strengthen its business competitiveness by expanding the Company's portfolio of technologies through continued development of innovative technologies. (AR)
