Abstract
A method and apparatus for reducing the emission of pollutants resulting from static test firings of rocket and jet engines. The apparatus comprises a test stand for capturing the exhaust gas from an engine undergoing a static test. The test stand includes a duct system for guiding the exhaust gas from a duct inlet to a duct outlet through stages that reduce the exhaust gas pollutants. Liquid oxygen ('LOX') is introduced into the duct system to interact with the engine exhaust gas stream. By introducing LOX, the pollutant CO is converted to non-pollutant carbon dioxide ('CO') as the exhaust stream moves through the duct system.
