“…The main advantage of PV over traditional methods such as distillation Membrane methods have shown great potential as efficient and low-cost separation processes. Currently, pervaporation (PV) as a membrane separation method has attracted great attention and covers a wide range of applications, including dehydration of organic media, removal of organic impurities from aqueous solutions, and separation of organicorganic mixtures [18,19]. PV has several significant advantages over traditional separation and purification methods, including high efficiency, low energy consumption, the absence of environmental contamination, and easy scale-up.…”

Ethylene glycol (EG) is an essential reagent in the chemical industry including polyester and antifreeze manufacture. In view of the constantly expanding field of EG applications, the search for and implementation of novel economical and environmentally friendly technologies for the separation of organic and aqueous–organic solutions remain an issue. Pervaporation is currently known to significantly reduce the energy and resource consumption of a manufacturer when obtaining high-purity components using automatic, easily scalable, and compact equipment. This review provides an overview of the current research and advances in the pervaporation of EG-containing mixtures (water/EG and methanol/EG), as well as a detailed analysis of the relationship of pervaporation performance with the membrane structure and properties of membrane materials. It is discussed that a controlled change in the structure and transport properties of a membrane is possible using modification methods such as treatment with organic solvents, introduction of nonvolatile additives, polymer blending, crosslinking, and heat treatment. The use of various modifiers is also described, and a particularly positive effect of membrane modification on the separation selectivity is highlighted. Among various polymers, hydrophilic PVA-based membranes stand out for optimal transport properties that they offer for EG dehydrating. Fabricating of TFC membranes with a microporous support layer appears to be a viable approach to the development of productivity without selectivity loss. Special attention is given to the recovery of methanol from EG, including extensive studies of the separation performance of polymer membranes. Membranes based on a CS/PVP blend with inorganic modifiers are specifically promising for methanol removal. With regard to polymer wettability properties, it is worth mentioning that membranes based on hydrophobic polymers (e.g., SPEEK, PBI/PEI, PEC, PPO) are capable of exhibiting much higher selectivity due to diffusion limitations.

“…In this process, distillation is usually the technique used to break the azeotrope, representing a costly and energy intensive method. Over the last decade, tremendous effort has been made in implementing PV as an alternative to such separation [ 86 ]. Of course, zeolites have also been proposed to separate such organic-organic mixture with the need for methanol selective materials.…”

Thanks to their well-defined molecular sieving and stability, zeolites have been proposed in selective membrane separations, such as gas separation and pervaporation. For instance, the incorporation of zeolites into polymer phases to generate composite (or mixed matrix) membranes revealed important advances in pervaporation. Therefore, the goal of this review is to compile and elucidate the latest advances (over the last 2-3 years) of zeolite applications in pervaporation membranes either combining zeolites or polymers. Here, particular emphasis has been focused on relevant insights and findings in using zeolites in pervaporative azeotropic separations and specific aided applications, together with novel concepts of membranes. A brief background of the pervaporation process is also given. According to the findings of this review, we provide future perspectives and recommendations for new researchers in the field.

“…3 Many membrane applications have been extensively investigated at laboratory scale and are being commercialized. [4][5][6][7][8][9][10] Today polymer membranes are used to concentrate and purify gas and liquid mixtures in micro-, ultra-, and nano-filtration, distillation, gas separation, pervaporation, and dialysis processes. Each application requires specific membrane properties, which becomes feasible with the development of novel membranes.…”

Poly(biquinoline dicarbohydrazide)-co-(bistrimelliteimide) methylene-bisanthranylide (PQHI) and its metal-polymer complex PQHI-Cu + containing several types of functional groups (hydrazide, carboxyl, amide, and imide fragments) were synthesized. Dense thin-film membranes were prepared to study transport properties of these polymers in the separation of a benzene and isopropanol (IPA) mixture via pervaporation. Comprehensive studies of structure, physical and mechanical properties of the novel membranes were carried out. Structure of the polymer films was characterized using scanning electron microscopy. Measurements of physical and mechanical properties showed good performance capabilities of polymers as membrane materials. Transport properties of the synthesized polymers in pervaporation of benzene-IPA mixtures were characterized by determination of total flux, separation factor, as well as permeability and selectivity of the films. It was experimentally found and confirmed by quantum chemical calculations that the novel PQHI-based membranes are benzene selective due to the presence of functional groups capable of H-bonding. The benzene/IPA separation factor is equal to 38 for the PQHI membrane in pervaporation of the mixture containing 20 wt% of benzene.
