【摘要】：目前計算機技術(shù)已經(jīng)是過程工業(yè)必不可少的重要工具,自上個世紀80年代開始,化工流程模擬軟件得到了足夠的重視和發(fā)展,出現(xiàn)了許多公司如AspenTech、Sim Sci等,但是各軟件公司獨立發(fā)展,互相不兼容。在AspenTech公司的倡議下,上個世紀90年代末歐盟制定并提出了CAPE-OPEN接口標準,即開放式計算機輔助過程工程接口標準,現(xiàn)已成為流程模擬軟件的通用標準�；瘜W反應(yīng)過程是化工過程研究的焦點和核心,由于其廣泛性和復(fù)雜性,反應(yīng)過程的模擬也是對全流程進行模擬的重點和難點。因此,開發(fā)在不同模擬軟件中通用的反應(yīng)器單元模塊,具有重要的實際意義。使用C++編程語言開發(fā)7個反應(yīng)器單元模塊和一個公共反應(yīng)組件,開發(fā)的組件完全遵循CAPE-OPEN標準,可以和支持CAPE-OPEN標準的主流模擬軟件,如Aspen Plus、Hysys等相互兼容。根據(jù)常用的分類方法,將反應(yīng)器根據(jù)模型的不同分為簡單反應(yīng)器、熱力學反應(yīng)器和動力學反應(yīng)器。首先,總結(jié)了各類反應(yīng)器的數(shù)學模型,并探討其求解方法,對不同反應(yīng)模型的適用條件進行了研究。然后,結(jié)合CAPE-OPEN標準,開發(fā)7個典型反應(yīng)器單元模塊:化學計量反應(yīng)器、收率反應(yīng)器、三率法反應(yīng)器、平衡反應(yīng)器、吉布斯自由能反應(yīng)器、連續(xù)攪拌釜式反應(yīng)器和平推流反應(yīng)器,此外還開發(fā)了一個公用的反應(yīng)模塊,包含一個通用反應(yīng)包,可以根據(jù)用戶提供的反應(yīng)參數(shù)計算反應(yīng)平衡和反應(yīng)動力學等多種反應(yīng)的性質(zhì)。開發(fā)得到的反應(yīng)器單元模塊可以被模擬軟件調(diào)用,并包含一個GUI界面用于獲取用戶指定的參數(shù)。在提供了足夠的參數(shù)并將模擬器的物流流股連接到單元模塊上之后,單元模塊可以進行反應(yīng)過程的模擬計算。最后,通過對實例進行計算,并將計算結(jié)果與其他權(quán)威流程模擬軟件相比較,結(jié)果表明:開發(fā)的數(shù)學模型和模塊可以對常見典型反應(yīng)過程進行模擬。本文所進行的CAPE-OPEN標準和反應(yīng)過程開發(fā)的結(jié)合,對于反應(yīng)過程模擬具有很強的基礎(chǔ)價值和實用價值,為開發(fā)更多復(fù)雜反應(yīng)器打下基礎(chǔ)。
[Abstract]:At present, computer technology has been an indispensable tool in the process industry. Since -20s, chemical process simulation software has been paid enough attention to and developed. Many companies, such as Aspen TechSim Sci, have emerged. However, the software companies developed independently and were incompatible with each other. At the initiative of AspenTech, at the end of -10s, the European Union formulated and put forward the CAPE-OPEN interface standard, that is, the open computer-aided process engineering interface standard. Chemical reaction process is the focus and core of chemical process research. Because of its universality and complexity, the simulation of reaction process is also the focal point and difficulty of the whole process simulation. It is of great practical significance to develop reactor unit modules which are commonly used in different simulation software. Seven reactor unit modules and one common reaction module are developed with C programming language, and the developed modules conform to the CAPE-OPEN standard completely. Compatible with mainstream simulation software that supports CAPE-OPEN standards, such as Aspen Plus Hysys. According to common classification methods, reactors are divided into simple reactors, thermodynamic reactors and kinetic reactors according to different models. The mathematical models of various reactors are summarized and their solution methods are discussed. The suitable conditions of different reaction models are studied. Then, seven typical reactor unit modules: stoichiometric reactor are developed in combination with CAPE-OPEN standard. A yield reactor, a three-rate reactor, a balanced reactor, a Gibbs free energy reactor, a continuous stirred tank reactor and a pusher reactor were developed. In addition, a common reaction module was developed, including a general reaction package. The properties of reaction equilibrium and reaction kinetics can be calculated according to the reaction parameters provided by the user. The developed reactor unit module can be called by the simulation software. It also contains a GUI interface to get the parameters specified by the user. After providing enough parameters and connecting the flow units of the simulator to the unit module, the unit module can simulate the reaction process. Through the calculation of an example, the results are compared with other authoritative flow simulation software. The results show that the developed mathematical models and modules can simulate common typical reaction processes. The combination of CAPE-OPEN standard and reaction process development in this paper has strong basic value and practical value for reaction process simulation. Lay the foundation for the development of more complex reactors.
