CB&I has been awarded a contract by Shenhua Ningxia Coal Industry Group for the license and engineering design of a grassroots petrochemicals complex to be built at Lingwu, Yinchuan City, Ningxia, in China. The complex will use CB&I’s proprietary Olefins Conversion Technology (OCT) to produce 196,000MTPA of polymer grade propylene and its Comonomer Production Technology (CPT) to produce and recover 20,000MTPA 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.”
