Abstract:
Process for controlling, or reducing, the level of oxidized anions, usually oxidized sulfur compounds or oxidized nitrogen compounds, in a reaction medium, preferably in a closed loop recirculating system. The process comprises withdrawing a purge stream from the reaction medium and reducing the oxidized anions in a reduction furnance 44 having a char bed 48. The reduced compounds are recovered from the reduction furnace as smelt 50. Where the reduced compounds are useful in the reaction medium from which the purge stream was withdrawn, the reduced compounds are preferably returned to the reaction medium for further use therein.
