摘要
采用Aspen Plus及Energy Analyzer软件对某企业乙烯装置深冷分离系统进行了流程模拟及换热网络用能分析,针对该系统关键操作参数开展了优化研究,并根据优化后的工艺操作参数对各等级冷剂的设置及冷量的分配提出了优化方案,模拟计算表明,深冷分离系统优化后,制冷压缩机功率减少6.64%,综合能耗降低5.46%。
With the software Aspen Plus and Energy Analyzer,the chilling separate system in ethylene plant was simulated,the energy use of heat exchanger network was analyzed,the key operation parameters of chilling separate system were optimized,and the optimization scheme of the refrigerant temperature and refrigerant allocation in refrigerant system was proposed.Simulations results showed the power of refrigeration compressors could be reduced by 6.64%and the comprehensive energy consumption could be reduced by 5.46%.
