【摘要】：精餾在化工生產(chǎn)中是一個非常復(fù)雜的混合物分離過程。隨著計算機的廣泛應(yīng)用,化工流程模擬軟件在化工中的應(yīng)用也越來越多,尤其是對精餾過程的模擬�；すに囬_發(fā)人員可以直接在計算機上對精餾塔的操作條件進行調(diào)節(jié),使其達(dá)到最優(yōu)的生產(chǎn)條件,并將其運用到生產(chǎn)實踐中。常見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)過程的核心部分,精餾過程的模擬也成為了化工過程模擬研究的熱點和難點。本文運用面向?qū)ο蠓椒ê蚔isual C++編程語言等在VS 2005軟件開發(fā)環(huán)境下,開發(fā)了遵循CAPE-OPEN標(biāo)準(zhǔn)的精餾塔單元模塊。經(jīng)過構(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,并對模塊的適用范圍進行了探究。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)以及進口參數(shù)后,在編譯得到的動態(tài)鏈接庫文件下便可以進行精餾過程的模擬計算。利用該精餾塔模塊對乙苯-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行精餾過程模擬計算。由模擬計算結(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。所開發(fā)的精餾塔單元模塊能夠用于精餾過程的模擬計算,并能夠在支持CAPE-OPEN的化工模擬軟件中調(diào)用。經(jīng)過實際精餾過程模擬計算驗證后,證明所開發(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)計規(guī)定、靈敏度分析等功能,使其能夠更好地進行精餾過程的模擬計算。
[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.
