一、概况我厂高含硫含氨污水单、双塔汽提装置,在回收精制液氨过程中,气氨进入填料式的氨精制塔内,进行循环洗涤,把气氨中的硫化氢脱除而达到精制目的.但往往由于操作不正常,气氨中含有较多的硫化氢对系统管线和设备产生腐蚀,硫化物等杂质堵塞了氨压机润滑油过滤网和机入口过滤网,造成停机,影响生产.经分析,沉积物中含硫
I. Overview I plant a high sulfur and ammonia-containing sewage single, double-stripping stripping device, the process of recovery of refined liquid ammonia, ammonia gas into the filler-type ammonia purification tower, the cycle of washing, the ammonia gas hydrogen sulfide off In addition to achieve the purpose of refining.But often due to the operation is not normal, ammonia contains more hydrogen sulfide on the system lines and equipment corrosion, sulfide and other impurities clog the ammonia compressor lubricating oil filter and machine inlet filter, resulting in Shut down, affecting production.After analysis, the sediment contains sulfur
