“…However, membrane units coupled with other separation methods (distillation, liquid-liquid extraction, adsorption, etc.) form the so-called hybrid separation processes that are feasible and cost-effective solutions [16,17]. Distillation is still the most popular separation method for a wide range of industrial problems (e.g.…”

“…The sequencing of separation operations depends on the relative advantages of each technology. When applied to a commercial-scale operation, as shown in Figure 2, the distillation operation is greatly enhanced (15,16). With PV, solvent can be more efficiently purified and dehydrated and then reused in the process.…”

The use of pervaporation technology as a green drying process for the recovery and reuse of the solvent, tetrahyrdofuran, in a pharmaceutical synthesis has been evaluated. A case study has been performed on a step in the synthesis of a new oncology drug. Pervaporation has been integrated with a constant volume distillation process to produce a hybrid system that allows for the recovery and reuse of tetrahydrofuran. An economic and environmental analysis shows that this is an effective technology for this application.

“…Pervaporation is a high potential industrial application for producing anhydrous ethanol. This method is not limited by vapor-liquid equilibrium, does not require use of toxic substances, and is a promising alternative to energy-consuming conventional techniques for separating ethanol mixtures [3][4][5][6]. Generally, pervaporation is expected to consume only 13% of energy as compared with azeotropic distillation [7].…”

A pervaporation process for producing anhydrous ethanol from industrial ethyl alcohol (95% v/v) was performed with a commercial PVA/PAN membrane. A central composite rotatable experimental design together with response surface methodology was implemented for studying and modeling the influence of operating conditions in terms of the temperature and the flow rate of the feed on the pervaporation performance, namely, the permeate flux and the separation factor. To obtain a trade-off between the permeate flux and the separation factor, a method for simultaneous optimization of multiple responses based on an overall desirability function was used. The optimization resulted in a feed temperature of 66 o C and a feed flow rate of 42 L/h. These operating conditions are expected to respond with a permeate flux of 0.107 kg/m 2 h and a separation factor of 40, which correspond to a satisfactory overall desirability.
