The reaction-separation integration for complex reactions was studied in this paper. The reaction-separation recycling system of Denbigh reaction was optimized and designed by a genetic algorithm. The relationship between process parameters and structure was analyzed. The results showed that there is the reaction-separation circular loop phenomenon for complex reaction systems including intermediates. The influence between reaction and separation was concentrated in the reaction-separation circular loop. The reaction-separation integration structure and the optimal process conditions are not only related with the reaction dynamics, but also with the reaction cost and separation difficulty. The integration structure would be changed in terms of different reactions or separation cost.
