摘要
流程工业开发的竞争力很大程度上取决缩短计算机辅助软件开发的周期,CAPE-OPEN(computer-aided process environment,OPEN)就是这样1套标准规范,它允许软件供应商、各研究机构及个人进行可兼容组件开发。这些组件以动态链接库的形式无缝构建了1个集成的模拟仿真环境。本文在现有精对苯二甲酸(pure terephthalic acid,PTA)全流程建模与仿真的基础上,将流程核心模块对二甲苯(p-Xylene,PX)氧化反应(continuous stirred tank reactor,CSTR)机理模型重构,封装成为符合国际流程工业接口标准CAPE-OPEN的独立组件,该组件通过开放(equation set object,ESO)接口,向数值求解器与仿真环境提供模型信息,调用CAPE-OPEN兼容物性包进行物性计算,从而完成模型的求解工作。该模块可与标准兼容流程仿真环境Aspen Plus交互,在该环境下将迭代求解结果与原流程模型仿真结果保持在0.1%以内,验证了模型的精确性与稳定性。
High competency of process industry entails relatively short life cycle of computer-aided software development. CAPE-OPEN is such a standard which allows commercial software vendors,organizations and individuals to codify their own advanced components.Wrapped into dynamic link library components,they can be utilized to seamlessly form an integrated simulation environment.In this paper we reconstruct a CSTR operation unit into a CAPE-OPEN compliant independent component. Through the open ESO interfaces it can provide the numerical information of the model mechanism.Physical property calculation procedure is accessed through CAPE-OPEN thermodynamic interface.The component has successfully communicated with the Aspen Plus Simulator.We have also provided effective methodology to guarantee the accuracy of the model.
