CB&I to license technology in China for production of propylene, butenes

08.26.2014  | 

The complex will use CB&I's proprietary olefins conversion technology (OCT) to produce 196,000 tpy of polymer grade propylene and recover 20,000 tpy of comonomer grade 1-butene.


CB&I was awarded a contract by Shenhua Ningxia Coal Industry Group Co. for the license and engineering design of a grassroots petrochemicals complex to be built in Lingwu, China, the company announced on Tuesday.

The complex will use CB&I's proprietary Olefins Conversion Technology (OCT) to produce 196,000 tpy of polymer-grade propylene and its Comonomer Production Technology (CPT) to produce and recover 20,000 tpy 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."

1- Mike Salem is definitely right. "most widely used" is a very bold statement which need to submit the supporting reference otherwise it is just a fallacy.
2- I wonder what is source of this Olefin feed? is it coming from Coal to Olefin plant Shenhua?

I wonder if the claim "Our Olefins Conversion Technology is the most widely used pathway for on-purpose polymer-grade propylene in the world" is accurate. I would like to see the data to support this claim against all other competing technologies and mainly UOP Olefin conversion technologies.
