摘　要: 该文介绍以氨为碱源的焦炉煤气湿式氧化法脱硫(HPF法)生产工艺系统投产以后,入脱硫塔焦炉煤气温度、再生系统空气量、脱硫循环液温度等指标的变化,从而使脱硫循环液中的(NH4)2S2O3、NH4CNS、(NH4)2SO4等脱硫副盐生成量加大,为了保证脱硫塔后焦炉煤气中H2S达到50PPm以下,必须提高外排脱硫液量,这些因素将增加焦炉煤气中的氨损失。由于再生后废气中携带有大量的氨气,被排放到大气中,也会使焦炉煤气中的氨产生损失。以上这些因素都会造成硫铵产率有大幅度的下降。

Abstract: The paper introduces that there is changes of quantities, such as coke oven gas temperature flowing into desulfurization tower , regeneration system air volume, and desulfurization circulation fluid temperature, after wet oxidation desulfurization(HPF) with ammonia as alkali source in coke oven gas was put into use, so that byproduct quantities of the desulfurization circulating fluid including (NH4)2S2O3, NH4CNS, (NH4)2SO4 increase. The discharging desulfurization liquid must increase in order to d in order to ensure that the desulfurization tower H2S in coke oven gas reaches 50PPm, and these factors will increase the loss of ammonia in coke oven gas. Because a large number of ammonia in the regeneration gas is emitted into the atmosphere, it also can make the ammonia loss in coke oven gas generation. These factors will cause ammonium sulfate yield greatly reduced.
