The complex will use CB&I's proprietary Olefins Conversion Technology (OCT) to produce 196,000 metric tons per annum (MTA) of polymer grade propylene and its Comonomer Production Technology (CPT) to produce and recover 20,000 MTA of comonomer grade 1-butene.
The complex at Shenhua Ningxia will also use the latest CDHydro® selective hydrogenation technology from CB&I, which allows the incorporation of different feed from the adjoining steam cracker into the downstream OCT unit. Additionally, CDIsis technology from CB&I will provide the conversion of isobutene into normal butenes, which increases the potential polymer grade propylene available from the steam cracker C4s.
"Our Olefins Conversion Technology is the most widely used pathway for on-purpose polymer grade propylene in the world," said Daniel McCarthy, President of CB&I's Technology operating group. "This project further demonstrates CB&I's capability to integrate our broad technology portfolio to meet our customers' needs."
