Abstract
Reactive dividing wall column (RDWC) is a novel thermal coupling technique in chemical engineering industry. For the reactive distillation system (RD system), which contains at least one reactive distillation column (RD) and one distillation column (DC), capital cost and energy consumption could be reduced by integrating the RD system to a RDWC.n this thesis, a reversible reaction ( ) was considered. For this reaction, Tung and Yu[47] and Lin et al.[31] proposed a series of RD system designs for different relative volatility rankings. Thus, we chose 6 two-column cases in these designs to discuss the characteristics of the RDWC.esides the simulation work of the RDWC, we proposed a simple but powerful method to estimate the energy consumption of the RDWC by the results of the optimal RD system. In this work, two-column cases and three-column cases were taken to test the precision of this method. The calculation results demonstrated that the accuracy of this method is promising.
