Mitsubishi Heavy Industries, Ltd., has been named builder for the expansion of Exxon Mobil Corp.’s polyethylene plant along U.S. 90 west of Beaumont, the company announced Wednesday.

Japan-based MHI, which earlier this year moved its North American headquarters to Houston, has received an order for reaction, finishing and shipping equipment, and water, air and steam facilities for the $1 billion project.

When complete in 2019, the plant will produce 650,000 tons per year of polyethylene, a chemical used to make plastic products including grocery bags and packaging, according to MHI.

The company also is building Exxon Mobil’s two-unit polyethylene facility — under construction in Mont Belvieu — and in 2011 built Exxon Mobil’s Singapore polyethylene plant.

The chemical plant is one of two large Exxon Mobil projects scheduled for the company’s Beaumont facilities. In July, the Irving-based petrochemical company announced a $450 million expansion of its Beaumont refinery.
