More recently, the concept of integrated forest biorefinery (IFBR) has received much attention as a promising solution for the struggling forest industry in North America and Europe to overcome its difficult financial period and competes globally. This new business paradigm offers a broad range of potentially attractive products, from bioenergy to value-added green organic chemicals in addition to traditional pulp and paper products. However, it also implies adoption of different types of appropriate separation technologies. Recent advancements in membrane technologies and their valuable applications have resulted in numerous breakthroughs in IFBR. The review of the implementation of membrane technologies for the separation of the value-added chemicals in the integrated forest biorefinery could contribute to the knowledge required for the large-scale adoption of membrane technologies in the forest industry. This paper aims to present a state-of-the-art review on the applications and the recent advancements of membrane technologies in IFBR, and their capacities to produce value-added chemicals and bioenergy. The emphasis is given to the focus areas of IFBR, particularly: the recovery of value-added chemicals, black liquor concentration, product recovery from Kraft evaporator condensates, tall oil recovery, inorganic and inorganic compounds recovery, fermentation inhibitors removal, enzyme recovery, biobutanol and bioethanol production and recovery. The paper also discusses the challenges and opportunities of this new business paradigm of forest industries.

Membrane technology applied in the chemical and energy industry has the potential to overcome many drawbacks of conventional technologies such as the need of large volume plants and large CO2 emissions. Recently, it has been reported that this technology might become more competitive when operated at high temperatures. This is mostly associated with the required of heat integration at large scale. However, good membrane stability combined with high permeation rates and high perm-selectivities, has only been achieved at intermediate/low temperatures (< 500 °C). When operated at these lower temperatures in a fully integrated plant, there is often the need of electricity import, which strongly decreases the process efciency and renders the membrane-based technology less competitive compared to conventional technologies. To improve the competitiveness of membrane technology further developments are required, demanding in particular an improvement in the preparation methods, the use of new materials and/or the development of novel reactor confgurations. In this study, a comprehensive review on the latest advancements in membrane technology for H2 separation at high temperature is presented. Special attention is given to the membranes prepared and presented in the literature in the last years for high-temperature applications, as well as the different membrane reactor confgurations that have proposed, tested and evaluated for different reaction systems at elevated temperatures. Since concerns about the need of high temperatures in membrane technology are relatively new, this review is limited to the results reported in the literature during the last five years.

Reverse osmosis (RO) technology has been widely applied to water treatment such as seawater desalination, and large RO plants are many in operation around the world. Moreover, much larger plants will be required to secure sufcient water resource in the near future because global water shortage and quality problems are still getting more serious. Mega-ton Water System project was carried out for sustainable management of water environment and for low-carbon path to develop advanced key technologies of water treatment. Lowpressure RO membrane for seawater desalination has been studied in the project as a part of the core technologies to realize mega plant that is capable of producing 1,000,000 m3 of freshwater per day. Fundamental and scientifc research for RO membranes based on fne structure analyses by means of transmission electron microscopy with a special technique was conducted, and practical tools for designing new innovative RO membrane were acquired by the structure analyses to quantify the physicochemical and chemical properties of RO membranes. As the result of studying on structural design of RO membrane, low pressure SWRO membrane was obtained to reduce energy consumption compared to conventional ones in the past of SWRO. The vision of the “Mega-ton Water System” is sustainable desalination and reclamation. The missions are: 1) energy reduction (20-30%), 2) water production cost reduction (50%), and 3) low environmental impact (fewer chemical operations). Water cycle in “Mega-ton Water System” is separated into two parts including i) Seawater RO (SWRO) system, and ii) Seawater RO system with PRO system. The main challenge of development goal is the construction of mega-ton-scale system for seawater desalination for half the current cost. Accordingly, we developed the world’s frst low-pressure, multi-stage, high yield RO system, using a low-pressure seawater desalination membrane, and as a result of incorporating into it the elemental technologies gained from research in subthemes, such as highly-efcient pressure energy recovery, low-cost and highly durable plastic piping, pretreatment without the use of chemicals.

Reverse osmosis (RO) is a water purifcation technology that uses a semipermeable membrane to remove ions, molecules, and larger particles for the production of drinking water. The frst RO membrane for seawater desalination, wastewater treatment and other applications were made of cellulose acetate. But, the polyamide thin-flm composite membrane that can tolerate wide pH ranges, higher temperatures, and harsh chemical environments is the most popular, currently. To further improve the membranes’ performances, the recent trend in polymer-based membrane research has been focused to investigate various types of nanocomposite membranes, in which nanosized fllers such as SMCNT, MWCNT, graphene, graphene oxide, silica, or zeolite are incorporated. However, there are many challenges to commercialize the application of these membranes. Nowadays, it is a norm to characterize membranes by the advanced characterization techniques such as Fourier transform infrared spectroscopy (ATR-FTIR), scanning electron microscope (SEM), atomic force microscopy (AFM), X-ray photoelectron spectroscopy (XPS), X-ray diffraction (XRD), Raman spectroscopy and others for studying the physical and chemical properties of membranes and to co-relate those properties to the performances of the membranes. In this work, different aspects of RO membranes and proposed characterization methods, as well as recent progresses have been reviewed, comprehensively.

Polymeric nanofbers, specifcally fabricated by electrospinning, offer viable means useful for a wide range of applications such as health, energy and environmental issues. However, among the mentioned sectors, desalination and water/wastewater treatment applications have been highlighted during the past decade. This article focuses on the present status and recent development of electrospun nanofbrous membranes and their potential impact in two major areas, i.e., desalination and water/wastewater treatment. Specifc applications for desalination and high-quality water/wastewater treatment, including pressure-driven and osmotic membrane processes (MF, UF, NF, FO, etc.), thermal-driven membrane processes, coalescing fltration and adsorptive application of nanofbers, are described. Also, benefts, limitations and challenges are discussed, comprehensively. Electrospun membranes can play a critical role in improving membrane-based desalination and water/wastewater treatment systems. These fltration elements with 3D inter-connected structures will be shown to have interesting and crucial advantages over conventional polymeric membranes in terms of performance, cost and energy savings. This article also highlights the prospects of electrospun membranes and specifcally provides the state-of-the-art applications in the water industry.

A Review of Electrospun Nanofber Membranes
Shahram
Tabe
Electrospun nanofber membranes (ENMs) are new generation of membranes with many favorable properties such as high flux and low pressure drop. Although electrospinning has been known for more than a century, its applications in fltration and separation processes are relatively new. Electrospinning has provided the means to produce ultrathin fbers – as thin as a few nanometers – that can be used in preparing membranes with small and defned pore sizes. In addition, due to the small fber diameter ENMs exhibit high surface area to volume ratio, making them suitable adsorption media with enhanced capacity compared with conventional adsorbents. This paper familiarizes the reader with the history and laboratory-scale preparation of ENMs, discusses parameters that influence properties of the fbers and the fnal membranes, and introduces a number of applications in which, ENMs have exhibited superior performances compared to competing conventional processes.

Functionalized and Electrospun Polymeric Materials as High-Performance Membranes for Direct Methanol Fuel Cell: A Review
Prakash
Mahanwar
Sumit
Bhattad
Proton exchange membranes (PEM) for a direct methanol fuel cell (DMFC) have main drawbacks which are methanol permeability, reduced proton conductivity and the cost of the membrane. This paper reviews different polymeric materials such as fluorinated, non-fluorinated, acid-base complex, and composite membranes for DMFC. Currently, nonfluorinated membranes gain a lot of attention due to their low cost. Many researchers have developed functionalization methods for non-fluorinated polymer electrolyte membranes for DMFC application to reduce the methanol crossover. Finally, this review presents the Electrospinning technique and its parameter for fabrication of PEM with functionalized polymeric materials by using electrospinning to solve the proton conductivity and methanol permeability problem. The last part of the paper describes the current studies and future direction of PEM for DMFC.

The Isolation of Organic Compounds using Organophilic Pervaporation Membranes

Organophilic membranes provide a method of recovering organic compounds by pervaporation, which exploits the selective transport of the organic phase. The main application is in the extraction of bio-alcohols from aqueous solution. The effect of membrane composition on performance in transporting alcohols and not water at improved rates is the focus of this review. In this way the minor fraction, the bio-fuel, is removed rather than the usually large volume of water. A more economical process is then obtained. The most successful membranes are non-polar in character, and can be purely organic, inorganic or organic-inorganic polymer hybrids. For ethanol recovery, flux rates are best for polydimethylsiloxane (PDMS) when used as a very thin layer on a supporting base. Zeolites give the best separation factors along with reasonable fluxes, and supported silicalite performs well. For butanol recovery, flux rates are best for PDMS mixed matrix membranes. A styrene copolymer membrane gives a reasonable result for benzene/cyclohexane separation, while metal-organic frameworks have potential in the separation of organic isomers, where pore geometry becomes important.
