摘　　要：以某项目乙烯精馏塔冷凝器为例,利用Aspen EDR软件,分析了操作液位对卧式容器内板翅式换热器的换热负荷、换热温差、冷气化率、冷剂出口气液夹带率、阻力降等因素的影响。通过这样的分析,可以指导设备设计和运行,得到符合工艺要求的,性能稳定的液位操作区间。Taking the condenser of an ethylene distillation tower as an example,using Aspen EDR software,the influence of operating liquid level on heat transfer load,heat transfer temperature difference,refrigerant vaporization rate,refrigerant outlet gas-liquid entrainment rate and resistance drop of horizontal core in vessel was analyzed.Through such analysis,the design and operation of the equipment can be guided,and the liquid level operation interval with stable performance can be obtained in line with the process requirements.
