摘要
萨南浅冷装置由氨制冷改为丙烷制冷后,制冷温度由原来的-25℃下降到目前的-35℃,装置运行时频繁发生冻堵。通过对冻堵位置和冻堵现象进行分析,找到产生冻堵的原因,对乙二醇加注量、乙二醇再生塔温度控制系统和二级三相分离器液位控制系统进行优化,避免装置冻堵,每年节省电加热器能源消耗16×104k Wh。
The refrigeration temperature in Sanan shallow refrigeration plant drops from-25℃.to-35℃ after its refrigerant changed from ammonia to propane,the shallow refrigeration plant use propane as a refrigerant instead of ammonia,which causes frozen blocking frequently.After studying the positions and phenomenon of frozen blocking,the reasons caused frozen blocking is found.The frozen blocking can be avoided by optimizing the injection amount of glycol solution,the temperature control in glycol regeneration tower and the liquid level control system in the second three-phase-separator.16×10~4 kWh of power for electric heater can be saved per year.
