Project: Air Emissions Testing, General Motors Corporation
Location: Defiance, Ohio

  

Description: A.S.T. performed air emissions testing on a regenerative catalytic oxidizer that is part of an aluminum casting line. The testing was conducted on the inlet and outlet simultaneously using Method 7E for the determination of NOx and Method 25A for the determination of Volatile Organic Compound (VOC) concentrations. We utilized a dual analyzer process during the test runs to obtain methane and total gaseous non-methane organic concentrations.
