摘要
对氨精制系统进行了技术改造。氨液循环泵由齿轮泵改为高速泵 ,效果较好。控制精制塔温度 ,尽可能减少水、H2 S携带入氨压缩机内 ,采用氨压缩机前脱水、吸附措施是有效的。
The ammonia refining system was revamped.Using high speed pumps to replace gear pumps for ammonia recycling,satisfactory results were achieved.Controlling the temperature of refining tower,eliminating entrainment of water and H 2S into the ammonia compressor as possible,dewatering and adsorpting before it was compressed,are effective measures.
