HPF DeSOx process is adopted in Qianan Zhonghua Coal Chemical Industry Co.,Ltd.,To reduce the suspended sulfur content in desulfurizing solution,blast intensity of regenerator shall be controlled at 100～110 m3/m2;sulfur paste in expansion area of regenerator shall be rinsed;sulfur melting shall be strengthened;foam thickness at regenerator top is controlled at 30～40 cm.Then the suspended sulfur in DeSOx solution is maintained below 0.2 g/L.Clear liquid system of sulfur melting pot is optimized to reduce manual labor and improve the operation environment.
