Abstract
Alkali metal chlorite, particularly sodium chlorite, is produced with a level of purity superior to that expected based on the composition of the chlorine dioxide generator off-gas that is used as a raw chemical feed for chlorite manufacture. The off-gas is preferably drawn before it enters the chlorine dioxide absorption tower and is passed through a conditioning stage to then react in a liquid medium to produce an alkali metal chlorite solution from which the unreacted and produced gases are immediately separated.
