Williams Partners LP’s repaired and expanded Geismar Olefins plant in Louisiana is expected to begin manufacturing ethylene for sale in November.

All major construction related to the rebuild of the plant, which was damaged in a 2013 explosion, the expansion project and the safety-related equipment installation is now complete, the company said Wednesday. The general contractors for the expansion and rebuild projects have demobilized and Williams’ operations personnel are now directing the dry-out and commissioning of the plant.

“We are in the final stages of commissioning and startup,” said John Dearborn, the partnership’s senior vice president of natural gas liquids and petchem services. “We fully expect to be manufacturing ethylene for sale in November, consistent with our financial guidance.”

Capacity at the plant is now 1.95 billion pounds of ethylene per year. Williams Partners’ share of the total capacity of the expanded plant is 1.7 billion pounds per year. Williams owns controlling interest and is the general partner of Williams Partners.

An explosion and fire in June 2013 at the facility killed one person and injured dozens (see Daily GPI, June 14, 2013). The restart had been planned for last June (see Daily GPI, May 2) but delays moved the planned restart to October (see Daily GPI, July 31).
