中国石油大庆炼化公司聚合物一厂丙烯腈装置频繁出现回收塔塔釜憋压、40#板以下塔板通量不畅的现象,造成回收塔系统波动较大,影响回收塔的稳定运行。通过采取降低装置负荷,暂时缓解了系统波动,但是对于装置的长周期运行造成严重影响。1回收塔憋压现象回收塔系统多次出现塔釜憋压现象,塔釜温度由正常运行时的116℃上涨至117℃,灵敏点温度下降,V-138、T-104液位大幅度波动。调
China Petroleum Daqing Refining & Chemical Company a polymer plant acrylonitrile plant frequent recirculation tower reactor pressure, 40 # plates below the plate flux is not smooth, resulting in large fluctuations in the recovery tower system, affecting the stable operation of the recovery tower. By taking a reduced load on the device, system fluctuations are temporarily relieved, but have a serious impact on the long-term operation of the device. 1 Recovery tower pressure phenomenon The recovery tower system appears many times the pressure of the tower kettle pressure, tower kettle temperature from 116 ℃ during normal operation rose to 117 ℃, sensitive point temperature dropped, V-138, T-104 liquid level fluctuations .
