-- Valero Energy Corp. has successfully started up advanced reformate splitters at refineries in Texas and Tennessee.

The three Mobile Source Air Toxic (MSAT) II benzene concentration units are at Valero's Port Arthur and Sunray, Tex., and Memphis, Tenn., refineries. They use advanced reformate splitter Dividing Wall Column towers conceived by Valero and designed and optimized by KBR.

A fourth unit at Valero’s St. Charles refinery in Norco, La., and will be commissioned later this year.

The DWC tower concentrates and removes benzene from gasoline streams to allow a refinery to meet US regulatory mandates limiting benzene content in motor gasoline.
