“…The obtained values for the methanol are in agreement with those found at the literature [5,[30][31][32]. As it was said, Nafion is not-crosslinked membrane; therefore the size of ionic clusters and hydrophobic regions may vary according to the solvent [19]. This fact could account for the different behavior observed for the water-alcohol solutions.…”

“…The experimental device is only briefly summarized here, since it is similar to the ones used in previous works [18][19][20]. Basically, the membrane was housed at a PTFE cell, consisting of two independent chambers with an approximate volume of 10 −4 m 3 , the active membrane area was 25.3 × 10 −4 m 2 .…”

The framework of non-equilibrium thermodynamics (NET) is used to derive heat and mass transport equations for pervaporation of a binary mixture in a membrane. In this study, the assumption of equilibrium of the sorbed phase in the membrane and the adjacent phases at the feed and permeate sides of the membrane is abandoned, defining the interface properties using local equilibrium. The transport equations have been used to model the pervaporation of a water-ethanol mixture, which is typically encountered in the dehydration of organics. The water and ethanol activities and temperature profiles are calculated taking mass and heat coupling effects and surfaces into account. The NET approach is deemed good because the temperature results provided by the model are comparable to experimental results available for water-alcohol systems.
