The potential of pervaporation for separation of acetic acid and water mixtures using polyphenylsulfone membranes

Effect of silica nanoparticles in mixed matrix membranes for pervaporation dehydration of acetic acid aqueous solution: plant-inspired dewatering systems

“…Details of the operation are explained elsewhere (Jullok et al, 2011(Jullok et al, , 2012(Jullok et al, , 2013.…”

“…Then, the membrane was again immersed in another clean water bath to remove traces of solvents. A similar synthesis procedure was described elsewhere (Jullok et al, 2011(Jullok et al, , 2012(Jullok et al, , 2013. Nine types of PPSU-based membranes, containing various concentrations and types of silica nanoparticles were prepared (see Table 2).…”

“…Since the separation of acetic acid from water using distillation has a very high energy cost making it inefficient, any cost-efficient method to dehydrate acetic acid is in demand. Among the proposed alternative methods, pervaporation has been suggested as a promising solution to separate acetic acid aqueous solution (Alghezawi et al, 2005;Durmaz-Hilmioglu et al, 2001;Huang et al, 1988;Jullok et al, 2011). Pervaporation is a membrane-based process that can be potentially applied to purify acetic acid (i.e., via acetic acid dehydration).…”

The driving force as key element to evaluate the pervaporation performance of multicomponent mixtures

“…An extensive research is being performed with the focus on pervaporation for dehydration of compounds or waste water treatment involving organic-water separations [1][2][3][4][5][6], and more recently, pervaporation of organic-organic mixtures, which is a more challenging separation due to the similar character of the compounds to be separated [7][8][9][10][11][12][13][14][15]. An example is transesterification reaction which is an equilibrium-limited reaction in which an ester and an alcohol are produced, involving a post-reaction organic-organic separation.…”
