Exxon Mobil Corp. says a new project to expand its Louisiana chemical and lubricant plants will bring more than 400 construction and full-time jobs to the state over the next two years.

Company officials said Thursday construction on the $200 million chemical and lubricants plants in Baton Rouge and Port Allen will begin at the end of the year.

The project is expected to make the company’s Baton Rouge plant the world’s largest producer of finished lubricants used in motor oils, gear oils and greases. The expanded 8.3-acre plant will replace an existing manufacturing facility in New Jersey.

Exxon already operates more than 30 facilities in the state.

Gov. Bobby Jindal says the expansion demonstrates the state’s continued commitment to retaining and growing Louisiana businesses.
