摘要:
为解决乙烯装置扩能后，热负荷需求升高的问题，对其丙烯系统中丙烯塔及碳三汽提塔的热负荷需求及供给能力进行了核算，并利用Aspen HYSYS软件对丙烯系统配套热源的3种扩能方案进行模拟计算及优化。结果表明：乙烯装置扩能后，需新增1套丙烯系统，与原丙烯系统并联运行，还需要补充热源以满足新增热负荷需求；采用新增丙烯系统中设置蒸汽再沸器、底部再沸器，不设中间再沸器，再沸器急冷水出口温度设为62 ℃的方案，能耗最低，可操作性最优。
Abstract:
In order to solve the problem of increased heat load demand after the capacity expansion of ethylene unit， the heat load demand and supply capacity of propylene tower and C3 stripper tower in the propylene system were calculated， and three kinds of heat source expansion schemes of propylene system were simulated and optimized by Aspen HYSYS software. The results showed that after the expansion of ethylene plant， an additional propylene system was needed to run in parallel with original propylene system， and heat source was needed to be added to meet the demand of the additional heat load. The scheme of setting the steam reboiler and bottom reboiler in the newly added propylene system without setting middle reboiler， and setting the outlet temperature of quench water of reboiler at 62 ℃ was adopted with the lowest energy consumption and the best operability.
