建立了分析和理解反应分离过程动力学的一般框架。该理论基于同时相和反应平衡的假设。它利用变换后的浓度变量，这是最先由Doherty和他的同事在反应精馏过程的稳态设计中引入的。罗伊SoC。伦敦A 413(1987A)459)。结果表明，这些变换后的变量可以直接推广到本文所考虑的动力学问题。此外，它们还可以应用于其他反应分离过程，如固定床和逆流色谱反应器。它们提供了对这些过程的动态行为的深刻洞察，并揭示了由反应共沸引起的可行操作的界限。结果表明，反应共沸是反应精馏中的一种常见现象。罗伊SoC。伦敦A413(1987b)443)在非常相似的条件下，在其他反应分离过程中也可能上升，例如，层析反应器。(C)2003爱思唯尔有限公司。保留所有权利。
A general framework for analyzing and understanding the dynamics of reactive separation processes is developed. The theory is based on the assumption of simultaneous phase and reaction equilibrium. It makes use of transformed concentration variables, which were first introduced by Doherty and co-workers for the steady state design of reactive distillation processes (Proc. Roy. Soc. London A 413 (1987a) 459). It is shown that these transformed variables can be directly generalized to the dynamic problem considered here. Further, they can also be applied to other reactive separation processes like fixed bed as well as countercurrent chromatographic reactors, for example. They provide profound insight into the dynamic behavior of these processes and reveal bounds of feasible operation caused by reactive azeotropy. It is shown that reactive azeotropy, which is a well-known phenomenon in reactive distillation (Proc. Roy. Soc. London A 413 (1987b) 443) may also rise under very similar conditions in other reactive separation processes like chromatographic reactors for example. (C) 2003 Elsevier Ltd. All rights reserved.
