摘要:
热集成精馏系统是精馏过程中有效的节能操作方式,节能效果可达50%.为了能够达到理想的节能效果,必须对这两个塔进行合理的操作和控制,否则,反而会影响正常的生产.但由于采用了该热集成操作方式,使得两个塔之间的关联变得十分严重,给系统的操作和控制带来了很大的难度.考虑热集成精馏系统的进料为主要干扰时,提出了在保证产品质量的前提下,以最小能耗为目标的动态优化和控制二级策略.在该二级策略中,上一级为以最小能耗为经济目标的动态优化,其优化结果作为下一级的优化给定值,下一级是跟踪上一级优化结果的多变量控制.
Abstract:
H eat integ ra tion d istillation sy stem is an effective m ethod o f sav ing ene rgy in the process o f d istilla tion, w ith 50% energy saved. To obta in an ideal energy sav ing effec t, we mustm ake a reasonable operation and contro l o f the two co lumns, o therw ise the no rma l produc tion w ill be a ffected. H owever, the adoption o f such heat integ ration opera tiona lm ethod leads to a severe association betw een the tw o co lum us, and thus a sign ifican t difficulty in operating and contro lling the system. W ith guarantee ing the qua lity of products as its precondition , and w ith them in imum cost of ene rgy as its purpose, th is paper suggests a secondary stragegy o f dynam ic optim ization and contro lwhen the feed o f the heat in teg ra ted distillation system is regarded as a m a in d isturbance. In the seconda ry strategy, the uppe r leve l is the econom ic optim ization w ith m inim um cost of energy as its purpo se, and its optim ized resu lt is the g iven va lue o f the optim ization of the lowe r leve ,l wh ich is the mu ltivar iable contro l to track the optima l reference tra jec to ries ca lculated on the upper level .
