【摘要】：精餾在化工生產(chǎn)中是一個(gè)非常復(fù)雜的混合物分離過(guò)程。隨著計(jì)算機(jī)的廣泛應(yīng)用,化工流程模擬軟件在化工中的應(yīng)用也越來(lái)越多,尤其是對(duì)精餾過(guò)程的模擬�；すに囬_(kāi)發(fā)人員可以直接在計(jì)算機(jī)上對(duì)精餾塔的操作條件進(jìn)行調(diào)節(jié),使其達(dá)到最優(yōu)的生產(chǎn)條件,并將其運(yùn)用到生產(chǎn)實(shí)踐中。常見(jiàn)的化工流程模擬軟件有Aspen Plus,PROII,Hysys,ChemCAD等。由于精餾分離是化工生產(chǎn)過(guò)程的核心部分,精餾過(guò)程的模擬也成為了化工過(guò)程模擬研究的熱點(diǎn)和難點(diǎn)。本文運(yùn)用面向?qū)ο蠓椒ê蚔isual C++編程語(yǔ)言等在VS 2005軟件開(kāi)發(fā)環(huán)境下,開(kāi)發(fā)了遵循CAPE-OPEN標(biāo)準(zhǔn)的精餾塔單元模塊。經(jīng)過(guò)構(gòu)建精餾塔單元操作模塊的穩(wěn)態(tài)數(shù)學(xué)模型,研究了精餾塔各種不同的求解算法,并對(duì)模塊的適用范圍進(jìn)行了探究。另外,還創(chuàng)建了精餾塔模塊的GUI界面。獲取精餾塔單元操作模塊的用戶界面上的操作參數(shù)以及進(jìn)口參數(shù)后,在編譯得到的動(dòng)態(tài)鏈接庫(kù)文件下便可以進(jìn)行精餾過(guò)程的模擬計(jì)算。利用該精餾塔模塊對(duì)乙苯-苯乙烯精餾塔、第二效蒸發(fā)精餾塔、氣分裝置烷基化原料塔進(jìn)行精餾過(guò)程模擬計(jì)算。由模擬計(jì)算結(jié)果可知,塔頂、塔底溫度以及出口流股的組成均與Aspen Plus結(jié)果基本一致,可以達(dá)到分離要求。所開(kāi)發(fā)的精餾塔單元模塊能夠用于精餾過(guò)程的模擬計(jì)算,并能夠在支持CAPE-OPEN的化工模擬軟件中調(diào)用。經(jīng)過(guò)實(shí)際精餾過(guò)程模擬計(jì)算驗(yàn)證后,證明所開(kāi)發(fā)的精餾塔單元操作模塊可用于極性和非極性物系的精餾分離。此外,在此基礎(chǔ)上還可以增加設(shè)計(jì)規(guī)定、靈敏度分析等功能,使其能夠更好地進(jìn)行精餾過(guò)程的模擬計(jì)算。
[Abstract]:Distillation is a very complex mixture separation process in chemical production. With the wide application of computer, chemical process simulation software is used more and more in chemical industry, especially in distillation process simulation. The chemical process developers can adjust the operation conditions of distillation column directly on the computer, make it reach the optimal production condition, and apply it to the production practice. The common chemical process simulation software includes Aspen Plusl Pro II Hysys Chemical CAD and so on. Because distillation separation is the core part of chemical production process, the simulation of distillation process has become a hot and difficult point in chemical process simulation. In this paper, using object-oriented method and Visual C programming language in vs 2005 software development environment, the distillation column unit module which conforms to the CAPE-OPEN standard is developed. By constructing the steady mathematical model of the unit operation module of distillation column, the various algorithms for solving the distillation column are studied, and the applicable range of the module is explored. In addition, the GUI interface of the distillation tower module is also created. After obtaining the operation parameters on the user interface and the inlet parameters of the unit operation module of the distillation column, the simulation calculation of the distillation process can be carried out under the compiled dynamic link library file. The distillation process of ethylbenzene-styrene distillation tower, the second-effect evaporation distillation tower and the alkylation feedstock tower of the gas separation unit were simulated and calculated by this distillation tower module. From the simulation results, it can be seen that the composition of the tower top, bottom temperature and outlet flow stock are basically consistent with the Aspen Plus results, which can meet the requirements of separation. The unit module of distillation column developed can be used in the simulation calculation of distillation process and can be called in the chemical simulation software supporting CAPE-OPEN. After the simulation calculation and verification of the actual distillation process, it is proved that the unit operation module developed in the distillation column can be used for the distillation separation of polar and non-polar systems. In addition, the functions of design specification and sensitivity analysis can be added on the basis of this, so that the simulation calculation of distillation process can be better carried out.
