The following points are emphasized:The operation models of adiabatic and diabatic distillation have been set up and the operation block, thermodynamics model and mathematical model in the simulation have been determined as well;(2)Based on the simulation and exergy analysis with Aspen Plus program, shortcut distillation design—DSTWU model and rigorous distillation design—RADFRAC model, the author has determined the heat duty, exergy losses and the distribution of exergy losses along the adiabatic column, which will help the simulation and optimization of the diabatic distillation;(3)Diabatic distillation under various operation conditions has been simulated by using energy balance method and exergy analysis;(4)How the different mixture and the various degree of separation, number of trays and feed location influence exergy saving in diabatic distillation have also been discussed;(5)On the basis of the total exergy losses along the column, different schema of the heat transfer distribution along the column have been compared and analyzed;they can be classified in three categories: heat duty equipartition approach, empirical approach, separation degree matching approach. In conclusion, different heat transfer distribution along the column will have effect on total exergy losses. In particular, most satisfactory results have been obtained by using separation degree matching approach. In order to diminish the exergy losses, heat transfer distribution should meet the needs of the request of separation degree.And on this premise, the author makes his suggestion in increasing the proportion of heat supplied to the tray with minimum exergy losses and decreasing the proportion of heat supplied to the tray with the maximum exergy losses.
本文对透热精馏过程进行了模拟并对其节能效果的影响因素做了较为全面的分析和深入的研究,主要研究内容如下:(1)建立了常规精馏和透热精馏过程的模拟操作模块、热力学模型以及数学模型;(2)利用化工模拟软件Aspen Plus并分别采用DSTWU简捷模型和RADFRAC严格计算模型对常规精馏进行模拟计算和有效能分析,确定常规精馏塔的公用工程热负荷、有效能损失及有效能损失在塔内的分布,为透热精馏的模拟和优化提供数据参考;(3)对不同物系在不同分离度条件下进行透热精馏的模拟,分别采用能量衡算法和有效能分析法进行计算和分析;(4)探讨了各种因素如物系的选择、不同分离度、塔板数、进料位置对透热精馏节能效果的影响;(5)以全塔总有效能损失为比较基准,对热量在塔内的三种分布方案即热负荷平均分配法、经验法和分离度匹配法进行了对比分析并得出结论:塔内热量的不同分布方案对于全塔总有效能损失会产生影响,其中以分离度匹配法的节能效果最为理想,为减少有效能的损失,应使塔内的热量分布满足各塔板的分离度要求,并在此前提下,尽量减小有效能损失大的塔板的热负荷和增加有效能损失小的塔板的热负荷。
