LIMA, Ohio -- Husky Energy Inc.'s Lima refinery plans to shut its selective catalytic reduction system for 10 days starting Monday for maintenance, said Dina Pierce, a spokesman for Ohio's Environmental Protection Agency.
The work involves the isocracker and ultraformer furnaces, Ms. Pierce said.
Production won't be affected, Mel Duvall, a Calgary-based spokesman for Husky, said. An ammonia tank that feeds the catalytic reduction system will be cleaned. An alternative ammonia system will be set up so production can continue, he said.
