【摘要】 流程模拟、先进控制和过程优化技术的研究与应用是企业提高效益的主要手段之一,而建立准确的系统模型是实现优化的重要前提。由于石化过程的复杂性,智能建模方法得到了广泛的应用。因此设计开发一个基于生产数据驱动的智能化实用数据处理、建模与优化集成的平台具有重要的实用价值。本文综合利用化学工程、系统工程、计算机、自动化技术,以大型石油化工生产过程为背景,研究石油化工过程的数据处理、过程建模与优化控制等技术,应用基于系统托管堆的动态链表以及多线程并行处理技术开发了基于数据流驱动的石化过程数据处理、建模与优化平台。平台的开发主要针对实验室从事的石油化工科研领域,同时兼顾其他领域的应用。平台采用组件化程序设计方法,设计了一系列具有良好的可重用性、语言无关性、高度开放性的软件组件。基于平台,快速地定制了高密度聚乙烯装置串级反应优化操作改造系统,系统在实际企业应用取得社会与经济效益,从而证明了平台的通用性、可移植性与定制方面的便捷性。更多还原

【Abstract】 Process simulation, advanced control and process optimization technologies are the main technical means for promoting the beneficial efficiency in enterprises. Then, building accurate system model is an important premise to realize the optimization. As petrochemical process is very complicated, Intelligence modeling method gets broad application. Thereby, there will be of great value to design and develop an intelligent integrated system based on data-driven, which is included by data processing, modeling and optimization.In this paper, by comprehensive utilizing chemical engineering, system engineering, computer, automation technology, taking large-scale petrochemical industry procedure of production as background, studying data processing, modeling and optimization technology in petrochemical process, using the component programming, a series of software components are designed with well-reusability, language-irrelevant and highly open-performance, a software system is developed by integrating data processing, modeling and optimization with dynamic chain based on managed heap and multi-thread parallel processing technologies。a modeling and optimization system is suitable for petrochemical process, and the social and economic benefit are obtained from the actual application in the enterprise.Based on that platform, HDPE Device cascade reaction optimizes operation reforming system has been customized rapidly. It proves applicability and portability of the platform and serviceability in customization.更多还原
