Pilot-scale exhaust gas treatment for a glass manufacturing system using a plasma combined wet chemical process

A novel technology for the simultaneous removal of NOx (= NO + NO2) and SOx (= SO2 + SO3) in the flue gas of a glass manufacturing system is described using a plasma-chemical hybrid process (PCHP). The exhaust gas is produced by combustion of liquefied natural gas and contains both NOx (189 - 335 pp...
