摘要
利用流程模拟软件Aspen Plus 10,借助系统模型推荐,选择Chao-Seader和Garyson-Streed热力学模型对中国石化茂名分公司4号柴油加氢装置分馏部分进行了模拟分析与优化,结果表明模拟计算结果与装置实际运行数据吻合良好。通过对分馏塔冷、热低压分离器油(简称低分油)进料位置及进料温度进行分析优化,同时配合换热流程匹配调整,以及冷、热低分油单独进塔改造,使得冷低分油换热终温提升至210℃,分馏过程汽提蒸汽流量减少1.7 t/h,节能效果显著。
With the help of Aspen Plus 10 and system model recommendation,the fractionator of No.4 diesel hydrogenation unit in SINOPEC Maoming Company was simulated,analyzed and optimized by Chao-Seader and Galyson-Streed thermodynamic models.The results show that the simulation results are in good agreement with the actual operation data of the unit.Through the analysis and optimization of feeding stage and feeding temperature of the cold and hot low pressure separator oil in the fractionator,and the matching adjustment of the heat exchanger flow,as well as the transformation of the cold and hot low pressure separator oil into the fractionator separately,the final heat exchange temperature of cold low pressure separator oil is raised to 210℃,the consumption of stripping steam in the fractionation process is reduced by 1.7 t/h,and the energy-saving effect is remarkable.
