Process intensification strategies and membrane engineering
Drioli, Enrico,Brunetti, Adele,Di Profio, Gianluca,Barbieri, Giuseppe The Royal Society of Chemistry 2012 Green chemistry Vol.14 No.6
<P>An important contribution to the realization of industrial sustainable development can be given by “green process engineering”. Based on the principles of the Process intensification strategy it can lead to the development and the re-design of new processes more compact and efficient that allow the better exploitation of raw materials, a lower energy consumption and a reduced plant volume. Membrane technology contributes to the pursuit of these principles and, in the last few years, the potentialities of membrane operations have been widely recognized. In this work, an overview of membrane application and their perspectives in the field of hydrogen production and distillation will be analysed considering membrane reactors and membrane distillation as case studies. The scope is to show how the redesign as membrane systems of traditional operations might contribute to the realization of the goals of process intensification and green chemistry by a new “green process engineering”.</P> <P>Graphic Abstract</P><P>Green chemistry and green process engineering also mean new processes such as those based on membrane reactors and membrane contactors. <IMG SRC='http://pubs.rsc.org/services/images/RSCpubs.ePlatform.Service.FreeContent.ImageService.svc/ImageService/image/GA?id=c2gc16668b'> </P>
Perspectives for Membrane Contactors Application in Water Treatment
Drioli, Enrico,Curcio, Efrem 한국공업화학회 2004 Journal of Industrial and Engineering Chemistry Vol.10 No.1
The possibility to redesign important industrial production cycles by combining various membrane operations is emerging as an attractive opportunity for the rationalisation of chemical productions. The field of applicability of traditional pressure driven membrane operations is today widened by novel membrane systems, such as membrane contactors. Potentialities of these devices have been discussed in the strategic sector of desalination and water treatment; here, despite the great success of membrane technology, some crucial problems still remains unsolved. Membrane absorbers and strippers can be used to control the amount of dissolved gases, thus reducing corrosion phenomena (O₂emoval), improving water agreeability (H₂S removal), adjusting pH (limitation of scaling potential, enhancement of rejection towards boron, control of polymorphism of precipitated species, etc.). Membrane distillation is able to overcome limitations suffered by RO operation, mainly due to concentration polarization phenomenon; as a result, the total water recovery factor can be drastically increased. Membrane crystallizers demonstrate interesting potentialities in the production of crystals from supersaturated solutions showing good structural properties. In addition, the design of the integrated membrane processes well satisfy the requirements for an advanced process intensification approach that, in perspective, promises to surmount the existing limits of industrial processing lines.
Membrane materials for addressing energy and environmental challenges.
Drioli, Enrico,Fontananova, Enrica Annual Reviews 2012 Annual review of chemical and biomolecular enginee Vol.3 No.-
<P>Our modern society must solve various severe problems to maintain and increase our quality of life: from water stress to global warming, to fossil fuel depletion, to environmental pollution. The process intensification (PI) strategy is expected to contribute to overcoming many of these issues by facilitating the transition from a resource-intensive to a knowledge-intensive industrial system that will guarantee sustainable growth. Membrane operations, which respond efficiently to the requirements of the PI strategy, have the potential to replace conventional energy-intensive separation techniques, which will boost the efficiency and reduce the environmental impact of separations as well as conversion processes. This work critically reviews the current status and emerging applications of (integrated) membrane operations with a special focus on energy and environmental applications.</P>
Membrane operations for produced water treatment
Drioli, Enrico,Ali, Aamer,Lee, Young Moo,Al-Sharif, Sharaf F.,Al-Beirutty, Mohammed,Macedonio, Francesca Balaban Publishers 2016 Desalination and Water Treatment Vol. No.
<P>Growing energy demand associated with improved living standards and rising population has increased the consumption of petroleum-based energy sources. To bridge the gap between demand and supply of petroleum-based energy resources, enhanced oil recovery and exploration of new nonconventional resources including shale gas, coal bed methane gas, and tight gas have gained popularity. These new techniques, however, use relatively fresh water and produce huge volumes of highly contaminated produced water. From compositional and potential treatment options, bilge water can also be included in the category of produced water. This work provides an overview of the investigations carried out for the removal of oil and greases using a membrane bioreactor and various other membrane operations. An analysis of a current and future scenario of produced water generated through conventional and nonconventional sources of energy and the perspective of produced water treatment in Saudi Arabia are also given. Finally, a cost estimation for the treatment of produced water using membrane operations is discussed.</P>
분리막 증류법을 위한 열전환된 폴리벤즈옥사졸 전기방사막의 제조

Membrane distillation (MD) has emerged as a next generation of desalination technique to resolve the limitation of RO process. In this study, Polybenzoxazoles(PBO) membrane via thermally rearrangement of polyimide containing hydroxyl groups was prepared [1]. The effect of operating conditions such as feed temperature, Reynolds number of feed flow and salt concentration of feed were investigated. TR polymer membranes were characterized by SEM, AFM and contact angle. Thermally rearranged polymers showed a potential to MD process with advantages of high flux and long-term stability during operation.

Membrane distillation (MD) has been researched as one of the promising seawater desalination processes, because of its advantages such as (1) high energy efficiency, high water flux and less fouling sensitivity. [1] Herein, thermally rearranged (TR) polymer membranes are introduced for MD application. The TR membranes were investigated by SEM, contact angle, CFP and LEPw. TR membranes showed a great MD performance with high water flux and long-term stability.

The increasing demand for materials, energy and products drives chemical engineers to propose new solutions everyday able to promote development while supporting sustainable industrial growth. Membrane engineering can offer significant assets to this development. Here, they are identified the most interesting aspects of membrane engineering in strategic industrial sectors such as water treatment, energy production and depletion and reuse of raw materials. The opportunity to integrate membrane units with innovative systems to exploit the potential advantages derived from their synergic uses is also emphasized. The analysis of the potentialities of these new technologies is supported by the introduction of process intensification metrics which provide an alternative and innovative point of view regarding the unit performance, highlighting important aspects characterizing the technology and not identified by the conventional analysis of the unit performance.

Since Loeb and Sourirajan has introduced phase inversion method for membrane fabrication, the phase separation technique became the mainstream of membrane fabrication methods. Phase inversion includes solvent evaporation, vapor induced phase separation, thermally induced phase separation (TIPS) and nonsolvent induced phase separation (NIPS). Among those, NIPS and TIPS process is widely studied and employed for membrane fabrication. Depending on the membrane fabrication processes such as NIPS and TIPS, corresponding morphology differs from macrovoid structure to spherulitic structure, respectively. In this presentation, comparison of NIPS and TIPS effect on the final membrane morphology and controlling the membrane morphology by tuning the NIPS and TIPS effect will be presented.
