摘要
对用环丁矾作溶剂的芳烃装置的用能进行分析,其中换热网络和分馏系统的节能潜力较大。采用夹点技术来提高换热网络的利用率,得到可行的节能方案;对芳烃分馏单元作4种节能方案研究,从中选择了最佳节能优化方案;最后对芳烃装置的整体节能方案进行探讨。
Analyzed the energy consumption of aromatics plant with sulfolane as the solvent, of which the heat exchanging network and fractionation system have bigger potency of saving energy. Feasible energy saving schedules were obtained by using pinch technology to increase the availability of heat exchanging network. Four energy saving schedules were studied for aromatics fractionation unit, and a optimal schedule was chosen. And finally the comprehensive schedule for aromatics plant energy saving was also discussed.
