半贫液再生效率评估-检测标准-检测项目-北检院

检测项目

再生效率：测定单位体积半贫液在再生过程中硫化氢的脱除率，反映再生塔的核心工作效能。

贫液残余硫化氢浓度：分析再生后贫液中未被氧化的硫化氢含量，直接关联下游吸收工序的净化度。

硫代硫酸钠浓度：监测副反应生成的硫代硫酸钠含量，其积累会降低有效溶剂浓度并可能引起设备腐蚀。

硫酸钠浓度：量化氧化副产物硫酸钠的生成量，过高浓度可能导致盐类结晶析出。

总碱度：检测溶液中活性碱组分的总含量，确保溶液具备足够的酸性气体吸收能力。

pH值：测量溶液的酸碱度，pH值影响吸收反应平衡与缓蚀剂的有效性。

溶液悬浮硫含量：测定溶液中单质硫的悬浮颗粒物浓度，过高会导致设备堵塞与发泡。

化学需氧量：评估溶液中有机降解产物及还原性物质的总体水平，指示溶液的老化程度。
