Abstract:

This paper introduces the determination for desulfurized liquor discharge volume with SCN^- balance according to the HPF reaction mechanism and actual production,with optimized results,such as ammonium thiosulfate around 60~80g/L,ammonium thiocyanate around 120~140g/L and that the volume of the discharged desulfurized liquor can be controlled at 30~35m³/day.
