CB&I to license technology in China for production of propylene, butenes
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
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
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.
CB&I's capability to integrate our broad technology
portfolio to meet our
