Adopting feed splitting in design of reactive distillation columns with two reactive sections

Feasibility of integrated batch reactive distillation columns for the optimal synthesis of ethyl benzoate

“…It is realized that 2.53% of conversion rate of BeZ can be improved at 0.925 of product purity as compared to that of the CBD system. Some researchers ignored the influences of azeotrope formation for the synthesis of isopropyl palmitate system due to higher conversion of palmitic acid of 99.40 % achieved in their work (Chen et al, 2012, Zhang et al, 2015. Note that, although both EtoH-H 2 O and EtBZ-H 2 O form minimum-boiling azeotropes, their impacts are neglected also in our work due to higher product purity of EtBZ and higher conversion level of BeZ into EtBZ are achieved (see Tables 3 and 5).…”

A novel split-reflux policy in batch reactive distillation for the optimum synthesis of a number of methyl esters

“…It can be seen from Table 6 also that higher product concentration of esters and higher conversion ratio of acids are accomplished. Some investigators disregarded the impacts of azeotrope formation and acid solubility for the production of isopropyl palmitate system due to the high conversion ratio of palmitic acid of 99.40 % accomplished in their work (Chen et al, 2012, Zhang et al, 2015. Note that, although the MeBZ-H 2 O form minimum-boiling azeotrope, their influences are ignored also in our work due to higher concentration of esters produced and higher conversion rate of carboxylic acids are attained by using the sr-BRD operation (see Tables 5 and 6).…”

Employing feed splitting to eliminate the black‐hole problem of dividing‐wall distillation columns

“…Feed splitting is a frequently used strategy for the synthesis and design of conventional and non‐conventional distillation columns because it can work as an effective means to reinforce mass and heat transfer within the processes . Feed splitting is often found to have favorable influences to process dynamic behaviors .…”

“…Eliminating the BH problem through feed splitting in process synthesis and design Feed splitting is a frequently used strategy for the synthesis and design of conventional and nonconventional distillation columns because it can work as an effective means to reinforce mass and heat transfer within the processes. [22][23][24][25] Feed splitting is often found to have favorable influences to process dynamic behaviors. [26] Regarding the DWDC, feed splitting can no doubt greatly affect the four connecting flows between the prefractionator and MDC involved and is therefore reasonable to be employed for the elimination of the BH problem during process synthesis and design.…”
