化工过程安全是绿色化工的主要研究内容之一。研究化学放热系统热失控临界判据,实质上就是确定反应系统安全操作区域,避免热失控行为的发生。本文对热失控-临界判据进行了详细总结,对各判据的优缺点进行了分析比较,提出了临界判据有效性的判定方法。最后,对非线性科学在放热系统热失控领域的研究进行了展望。
Chemical process safety is one of the main research areas in green chemical technology. The study of thermal runaway critical criteria in chemical exothermic system is mainly to determine safe operating area and to avoid thermal runaway. This paper summarizes the critical criteria of thermal runaway, analyzes their advantages and disadvantages, and presents the approaches for the evaluation of their effectiveness. Finally, the prospect of nonlinear science application in thermal runaway of chemical exothermic system is presented.
