摘要
通过实验研究了乙二胺/磷酸溶液在填料塔中的脱硫性能。考察了吸收液在不同的液气比、温度、pH值、浓度、SO2含量下的脱硫率,从而确立了适宜的工艺操作条件。适宜的操作条件为:液气比L/G=0 6～1 0,乙二胺浓度为0 3mol/L左右,pH值=6 0～7 5,吸收温度为4060℃,吸收液入口SO2质量浓度为6～8g/L。
The flue gas desulfurization capability of ethylenediami ne /phosphoric acid solution in packing tower was studied.The desulfurization effic iency of absorbing solution was investigated under different ratio of liquid to gas,temperature,pH,concentration and the content of sulfur dioxide.Experimental results indicated that the appropriate operational conditions were ratio of liqu id to gas L/G=06-10,concentration of ethylenediamine 03 mol/L,pH=60 -75,absorption temperature 40-60 ℃ and SO2 mass concentration of inlet abs orbent 6-8 g/L.
