Abstract

In industrial processes such as drying, glueing, and coating, huge air streams become loaded with solvents. For economical and environmental reasons these solvents should be reused. Composite membranes produced in hollow fiber form using polydimethylsiloxane as the selective barrier are tested to recover these solvents. A hollow fiber module was built into a closed loop and the solvent was removed from the air-acetone stream inside. To characterize the essential process parameters, stationary and non-stationary experiments were performed and their results compared. The economical evaluation shows a recovery cost of 0.41 DM/kg solvent, which leads to a time for the return of investment of 1.7 years.

A review on electrospun membranes for potential air filtration application
2022, Journal of Environmental Chemical Engineering
Citation Excerpt :
Polydimethylsiloxane (PDMS) and polyimide (PI) are typical membrane materials for the removal of VOCs, including acetone, toluene, and xylene, from air or N2. PDMS, for instance, displays selectivity values ranging from 11 to 25 in separating acetone [163,165], a selectivity of approximately 84 for toluene and a CO2/N2 ideal selectivity of 21 [166]. Rebollar-Perez et al. [167] investigated the application of PDMS/α-alumina membranes for vapor permeation, constructing a device to remove VOCs from air currents (at feed pressure: 3 bar and temperature: 21 °C).
Air pollution is one of the major environmental concerns in most highly populated cities, which is typically caused by particulate (PM_2.5 and PM_0.1) or gaseous pollutants. In this framework, membranes produced by the electrospinning technique are attracting more and more interest thanks to their peculiar properties such as interconnected pore structure, tunable porosity and fiber dimension, high surface area to volume ratio and controllable morphology. This review aims to provide an exhaustive overview on the electrospun membranes applied in air filtration introducing the key principles and fundamentals of the separation mechanisms and discussing the influence of membrane properties (e.g., morphology and charge) on their filtration efficiency. The materials generally employed for the fabrication of electrospun membranes (polymers, solvents) and their combination with additives with defined properties are reviewed also in light of the new environmentally friendly approaches which are increasingly adopted in membrane fabrication. Finally, the practical use of electrospun membranes in several application fields such as individual protection devices, environmental remediation, recovery of volatile organic compounds (VOCs), and ventilation and climate control aspects is widely discussed providing also an outlook on the upscaling potential of electrospun membranes and future directions.
Membranes for air cleaning
2022, Current Trends and Future Developments on (Bio-) Membranes: Membrane Technologies in Environmental Protection and Public Health: Challenges and Opportunities
Air pollution causes several problems for human health and environment. Membrane air cleaning is a recent technology, still under development, that improves the air filtration efficiency through higher performing devices with respect to the traditional ones. In this regard, the chapter deals with the most useful membrane separation techniques for air cleaning. Furthermore, the growing importance in air cleaning applications of polymeric, mixed matrix, and inorganics membranes, produced by different techniques (e.g., phase inversion, electrospinning) and under different configurations (hollow fibers, flat sheet and nanofibers), was also discussed. Meanwhile, the materials used for their preparation and related properties have been well identified and illustrated, paying particular attention to the main areas of application such as protection devices, air conditioners, and recovery (from air) of vapors of organic substances units.
Electrospun membranes for air filtration
2022, Electrospun and Nanofibrous Membranes: Principles and Applications
This chapter focuses on electrospun membranes produced by the electrospinning process for air filtration applications. Air pollution, above all in metropolitan and highly populated cities, can be characterized by particulate (PM2.5 and PM0.1) or gaseous pollutants that can be captured by different mechanisms employing electrospun membranes. The filtration efficiency can be influenced by their properties. Electrospun membranes are characterized by different advantages such as uniform and controllable structure, tunable porosity, and high surface area. Electrospinning is the most employed technique for the production of nanofiber membranes used in air filtration. The materials that can be employed for their production have been well investigated and most of them rely on polymers and biopolymers that are fundamental for determining the overall membrane performance. The presence of additives is often crucial for giving specific properties to the final membrane. Individual protection devices and uses for environmental remediation are the two main areas where electrospun membranes find application in the air filtration sector.
Pyrolysis of brominated polyethylene as an alternative carbon fibre precursor
2020, Polymer Degradation and Stability
Polyethylene as a polymeric precursor for carbon fibre production has attracted much attention over recent years. Not only is it a low-cost commodity polymer, it has a higher theoretical carbon yield (at 100%) than polyacrylonitrile (at 67%) and is very readily melt processed into fibres. The challenge is to efficiently dehydrogenate and graphitize polyethylene fibres. This paper explores the use of bromine as a novel oxidant to functionalise polyethylene prior to carbonisation, leading to efficient cyclisation and carbonisation on heating. Through a process of low-temperature photo-induced liquid-phase bromination followed by dehydrobromination at moderate temperature and subsequent carbonisation to 800 °C, a carbonaceous product was obtained in high carbon yield (>90%). The effects of a range of process conditions, as well as the use of different types of polyethylene and polyethylene blends, were explored.
Characterization of novel polydimethylsiloxane (PDMS) and copolymer polyvinyl chloride-co-vinyl acetate (PVCA) enhanced polymer blend membranes for CO<inf>2</inf> separation

Kimmerle et al. worked on blocking the air and allow the acetone to pass through the membrane at varying pressures. They also tried to alter the structure of the membrane by incorporating fillers to see how it impacts the permeability e.g. in their study they added Carbon Nanotubes (CNTs) and found that it increased the permeability for methane [40]. Membrane structures with low free volume tend to have low permeations; membrane permeability gets affected in harsh chemical environments and high temperatures, they are prone to plasticization thus reducing their selectivity [29,41].
An absolutely novel membrane of Poly (vinylchloride-co-vinylacetate) (PVCA) copolymer and polydimethylsiloxane (PDMS) with five different ratios were fabricated and used for further characterizations. Dense membranes of 50 μm were synthesized with ratios of PDMS and PVCA 99:1, 98:2, 97:3, 96:4 and 95:5 respectively. The separation performance is characterized by permeation studies of pure gases CO₂, N₂ and CH₄ at two different temperatures i.e. 25 °C and 75 °C and pressure of 10 psi. The ratio of PDMS:PVCA (96:4) showed the maximum ideal selectivity of (21.1) and permeability (5595 barrer) at 25 °C for CO₂/N₂ and CO₂ respectively. Further studies reveal that at a temperature of 25 ^OC membranes had high flux and higher selectivity. As the temperature was increased up to 75 ^OC the membranes showed the reverse behavior. Further it was found that addition of PVCA also improved the mechanical and thermal stability by 23.56% and 6.45% respectively.
Treatment efficiency and economic feasibility of biological oxidation, membrane filtration and separation processes, and advanced oxidation for the purification and valorization of olive mill wastewater

The difference in pH across the membrane maintains the concentration driving force for phenols, since the effective phenol concentration on the strip side is close to zero. The selective composite membrane, which was developed based on well-known methods (Strathmann, 1975; Ward et al., 1976; Baker et al., 1987; Kimmerle et al., 1988) and used in the contactor (membrane area: 21 cm2 and receiving volume: 0.5 L) is stable at extreme pH values and allows permeation of the neutral organic species from the acidic feed through the permeate, where it is ionized and becomes membrane impermeable. Therefore, the ionized phenolate in the stripping solution cannot diffuse back into the wastewater, resulting in a phenol concentrate in the permeate stream.
Olive mill wastewater (OMW) is a major waste stream resulting from numerous operations that occur during the production stages of olive oil. The resulting effluent contains various organic and inorganic contaminants and its environmental impact can be notable. The present work aims at investigating the efficiency of (i) jet-loop reactor with ultrafiltration (UF) membrane system (Jacto.MBR), (ii) solar photo-Fenton oxidation after coagulation/flocculation pre-treatment and (iii) integrated membrane filtration processes (i.e. UF/nanofiltration (NF)) used for the treatment of OMW. According to the results, the efficiency of the biological treatment was high, equal to 90% COD and 80% total phenolic compounds (TPh) removal. A COD removal higher than 94% was achieved by applying the solar photo-Fenton oxidation process as post-treatment of coagulation/flocculation of OMW, while the phenolic fraction was completely eliminated. The combined UF/NF process resulted in very high conductivity and COD removal, up to 90% and 95%, respectively, while TPh were concentrated in the NF concentrate stream (i.e. 93% concentration). Quite important is the fact that the NF concentrate, a valuable and polyphenol rich stream, can be further valorized in various industries (e.g. food, pharmaceutical, etc.). The above treatment processes were found also to be able to reduce the initial OMW phytotoxicity at greenhouse experiments; with the effluent stream of solar photo-Fenton process to be the least phytotoxic compared to the other treated effluents. A SWOT (Strength, Weakness, Opportunities, Threats) analysis was performed, in order to determine both the strengths of each technology, as well as the possible obstacles that need to overcome for achieving the desired levels of treatment. Finally, an economic evaluation of the tested technologies was performed in an effort to measure the applicability and viability of these systems at real scale; highlighting that the cost cannot be regarded as a 'cut off criterion', since the most cost-effective option in not always the optimum one.
