Method for carbon monoxide reduction during thermal/wet abatement of organic compounds

A thermal reactor system for oxidative treatment of gaseous pollutants in a gas stream, the system comprising:

• a combustion chamber having an entry end comprising at least one gas stream inlet for introducing combustible gaseous products and an exit end for removal of combustion products from the combustion chamber;
• a hot zone within the combustion chamber located adjacent to the entry end wherein gases entering the combustion chamber react and mix;
• an orifice in the combustion chamber communicatively connected to a source of compressed air to introduce oxygen enriched air into the central area of the combustion chamber, the orifice located downstream of the hot zone and downstream from the gas stream inlet for introducing combustible gaseous pollutants;
• and
• an oxygen separation unit positioned between the orifice and the source of compressed air to introduced oxygen enriched air to the hot zone of the combustion chamber to increase complete combustion and reduce formation of carbon monoxide.

A method for retrofitting an abatement system for processing a gaseous waste stream to introduce an oxygen-enriched gas therein and remove surface deposits within an abatement chamber having a hot zone and an inlet orifice for introducing the oxygen-enriched gas therein, wherein the inlet orifice is positioned downstream from the hot zone, the method comprising:

• providing an oxygen-enriching device communicatively connected to the abatement chamber;
• introducing compressed dry air to the oxygen-enriching device wherein the compressed dry air is separated into an oxygen-rich gaseous component and a nitrogen-rich gaseous component;
• introducing the oxygen-rich gaseous component into the hotzone of the abatement chamber through a centrally positioned orifice which is positioned downstream from the hotzone;
• and
• providing a mechanical scraping device in the abatement chamber.
