“…Pervaporation is a unique procedure that is rarely used as a separation process, but is clearly aligned with distillation [1,2] extraction [3], adsorption [4] and other processes. Hybrid processes for the synthesis of esters by esterification with pervaporation have been investigated [5][6][7][8][9][10][11].…”

“…An effluent containing THF, ethanol, and water is usually produced in some chemical and pharmaceutical processes, such as the wastewater from the production process of norgestrel, which would cause environmental problems and a waste of resources if not handled appropriately. Among the various separation processes, distillation has become the most common process for the separation of mixtures due to its inimitable advantages in application and control . However, it is difficult to implement the separation of THF/ethanol/water effectively by conventional distillation due to the presence of azeotropes.…”

BACKGROUND: There are three binary azeotropes in the tetrahydrofuran/ethanol/water ternary system at atmospheric pressure. Ternary extractive distillation (ED) processes were studied to separate the ternary azeotropic mixture using two single component solvents and a mixed solvent as entrainer.RESULT: Based on the sequential iterative optimization procedure, the minimal total annual costs (TACs) of the ternary extractive distillation process using ethylene glycol (EG), dimethyl sulfoxide (DMSO), and the mixture of DMSO and EG as entrainer were obtained. Compared with two single component entrainers DMSO and EG, the TAC of the extractive distillation process with mixed entrainer (60 mol% DMSO + 40 mol% EG) decreases by 6.55% and 31.88%, respectively. Furthermore, the reboiler heat duties of two extractive distillation columns (EDCs) with mixed entrainer were compared with two single component entrainers. CONCLUSION:The results show that the optimal ED process using mixed entrainer performs better than that using single component entrainers from the perspective of economics. Moreover, there is a tradeoff between the reboiler heat duties of two EDCs, which can be adjusted by changing the entrainer performance in two EDCs. The use of mixed entrainer enhances the flexibility of the tradeoff because it only needs to change the composition of the mixed entrainer.

“…To overcome these constraints, membrane integrated hybrid processes have been developed to optimize the productivity of separation processes. Integrating two unit operations with different separation principles may have a synergetic effect, and the resulting separation may be better than the separation obtained with either unit operation alone …”

Please cite this article as doi: 10.1002/jctb.5186 CONCLUSION: Incorporating pervaporation modules in the process flowsheet for production of ETBE allows to unload the main separation unit (debutanizer column), thereby reducing energy consumption and operating costs and increasing throughput.
