Abstract: Most chemical production process is intermittent, with the low degree of automation, high process complexity, strict conditions, high risk, etc.The traditional means of research and development is of high risk, cycle is long, and need to consume large amounts of manpower, material resources and financial resources.However, modern simulation technology is used to establish a set of virtual manufacturing system, people can work in the relevant scientific research out of danger; save the high costs which is required in practical research; dynamic structures and analysis reaction process, optimize process parameters, accelerate the research process of chemical production; have human-computer interaction with the built process,observe the working condition and reaction phenomenon of related equipment in real time; point of failure can be set and the process parameters can be changed artificially, also provides a new thinking and practice for operation training and emergency drill; to provide effective support for the chemical process simulation and the three-dimensional monitoring of production process.This paper introduces the recent progress in the field of modern chemical simulation technology at home and abroad and discusses its development trend.

Key words: modern chemical simulation technology, virtual reality, simulation training system, process simulation

摘要： 化工生产过程普遍存在间歇过程多、自动化程度低、工艺复杂、条件苛刻、危险性高等特点。传统的过程研究及开发手段风险大、周期长,需要消耗大量的人力、物力、财力。而利用现代仿真技术建立一套虚拟生产系统,人们可在没有危险的情况下从事相关科研工作;节省实际研究中所需的高额成本;动态搭建并分析反应流程,优化工艺参数,加快整个化工生产研究的进程;与搭建的流程进行人机交互,实时观察各相关设备的工作状态和反应现象;可人为设置故障点,或改变工艺参数, 为应急演练和操作培训提供一种新的思路和实践;为开展化工流程模拟、仿真培训与生产过程可视化监控提供有效的支持。本文介绍了最近国内外在现代化工仿真技术领域取得的进展并探讨了其未来的发展趋势。
