摘要:

乙烯精馏塔分离出产品乙烯,该塔控制的好坏直接影响乙烯产品质量和回收率,利用Aspen Plus 模拟软件对乙烯装置的乙烯精馏塔进行了模拟分析,确定了乙烯精馏塔进料塔板、灵敏板位置,并通过灵敏度分析得到各工艺参数对乙烯产品规格的影响。通过模拟指导,乙烯精馏塔增加灵敏板温度控制,塔釜液位控制,优化乙烯精馏塔压与回流量的控制,实现了增加乙烯产量、降低能源消耗,提高装置的总体经济效益之目的。

Abstract:

Ethylene rectifying column is used to separate ethylene product, and its control directly affects the quality and yield of ethylene product. Aspen Plus simulation software was used to analyze the ethylene rectifying column of ethylene plant. The positions of feed tray and sensitive plate in ethylene rectifying column were determined, and the influences of process parameters on ethylene product specifications were obtained by sensitivity analysis. Guided by the simulation, the temperature control of sensitive plate and the level control of tower bottoms were installed, and the control of pressure and return flow in ethylene rectifying tower were optimized, thus increasing the output of ethylene, reducing the energy consumption and improving the overall economic benefit of the plant.
