The mass transfer parameters needed for the design of a pervaporation process for the dehydration of isopropanol/water mixtures were obtained.
The membrane performances were tested in the pervaporation (PV) process for the dehydration of 90 wt% ethanol/water mixtures at 75°CC.
In particular, the potential of the process for the dehydration of an aqueous solution containing solid polystryrene microparticles (7 μm) was investigated and the unit was named vacuum membrane dryer (VMDr).
The preliminary economical evaluation of this process was compared with that of conventional distillation process for the dehydration of benzene, which showed that the PV process had economical superiority over the conventional distillation.
The information collected is of most importance to design and optimize a pervaporation process for the dehydration of n-butanol, which can be integrated with an intensified technology, the simulated moving bed reactor, used in the synthesis of the green fuel, 1,1-dibutoxyethane.
Thus, a novel and energy efficient Saline Entrainer Extractive Distillation (SEED) process is investigated for the dehydration of 2M2P, which utilizes an organic solvent: glycerol and an inorganic salt: MgCl2, as an effectual combined entrainer.
These pilot experimental results provided basic dada for industrial process design on the dehydration of benzene by PV.
