  • Method for reducing CO and VOC's in steelmaking furnace off-gas stream without forming or exhausting undesirable products
    Patent number: 6372009
    Abstract: A process and apparatus for continuously reducing carbon monoxide (CO), uncombined free hydrogen (H2) and volatile hydrocarbons (VOC's) in molten metal refining vessel off-gases without forming undesirable oxides of nitrogen. Off-gases are directed to a reaction chamber wherein CO, H2 and VOC's are oxidized at a controlled temperature and with a controlled quantity of O2 So as to realize substantially total oxidation of gases present with minimized formation of oxides of nitrogen. Volume and energy of treated gases directed for baghouse treatment are reduced in comparison with prior practice.
