Calgon Carbon Corp. was awarded a three-year contract by a petroleum refining company in the Midwest to supply 30 carbon adsorption systems and reactivation services to control vapor emissions. The value of the contract will depend upon the amount of spent activated carbon that is reactivated annually, which is expected to be in excess of 2 million lb per year. The refinery is using the carbon adsorption system to capture vapor during venting operations in compliance with Benzene/National Emission Standards for Hazardous Air Pollutants clean air regulations. The carbon adsorption systems consist of 30 VAPORPAC10 vessels, each containing 12,500 lb of granular activated carbon (GAC). When the GAC is spent, it will be taken from the refining site and reactivated at Calgon Carbon's Catlettsburg, Ky., facility. "We are pleased to have been awarded this three-year project," said Lisa Reese, vice president of Calgon Carbon's Industrial Business Unit.
