BP Amoco is operating one of two chemical production units at its Berkeley County plant after a $25 million fire Saturday.

The oil and chemical giant on the Cooper River suffered extensive damage to a compressor building in the early-afternoon blaze that was brought under control in about 45 minutes. No one was injured.

BP spokesman Scott Dean said the company shut down one of the two purified terephthalic acid, or TPA, production units as a result of the fire.

"BP is assessing the extent of damage to the compressor building and working to get the unit safely restarted," Dean said. "The rest of the Cooper River plant continues to operate and produce TPA for customers."

TPA is used in polyester fibers, paint, pharmaceuticals and various other applications.
