As part of the deal, the company will be involved in the engineering, procurement and construction of an ethane cracker and associated utilities and offsite to be located at OxyChem’s complex in Ingleside, Texas.

The cracker is expected to produce around 1.2 billion pounds of ethylene per year, while feedstock for the cracker is expected to be ethane derived from domestic shale gas.

CB&I president and CEO Philip Asherman said the ethylene project in the US reflects the quality of work, the company has provided to OxyChem and MexiChem to date.

"It shows the clients’ confidence in our ability to provide a complete range of services from proven licensed process technology, fabrication and FEED services to engineered products, all the way through to EPC," Asherman added.
