摘      要：In this work,the impact of internal heat integration upon process dynamics and controllability by superposing reactive section onto stripping section,relocating feed locations,and redistributing catalyst within the reactive section is explored based on a hypothetical ideal reactive distillation system containing an exothermic reaction:A + BC + *** state operation analysis and closed-loop controllability evaluation are carried out by comparing the process designs with and without the consideration of internal heat *** superposing reactive section onto stripping section,favorable effect is aroused due to its low sensitivities to the changes in operating *** ascending the lower feed stage,somewhat detrimental effect occurs because of the accompanied adverse internal heat integration and strong sensitivity to the changes in operating *** descending the upper feed stage,serious detrimental effect happens because of the introduced adverse internal heat integration and strong sensitivity to the changes in operating *** redistributing catalyst in the reactive section,fairly small negative influence is aroused by the sensitivity to the changes in operating *** reinforcing internal heat integration with a combinatorial use of these three strategies,the decent of the upper feed stage should be avoided in process *** the conclusions are derived based on the hypothetical ideal reactive distillation column studied,they are considered to be of general significance to the design and operation of other reactive distillation columns.
