WAPT, 3/7/8

Chevron Corp., the second-largest U.S. oil company, said Thursday that it plans to build a test plant at its refinery in Pascagoula, Miss.

The plant will test a process that could boost the yields of products refined from heavy oil.

Construction on the plant, which has already received needed permits, will begin later this year. The facility will have a daily capacity of 3,500 barrels, and will use a process in development since 2003 to refine heavy oil into gasoline, diesel and jet fuel.
