Process Intensification (PI) has been emerging as a novel processing philosophy fit for the needs of the new millennia as a result of global warming, concerns for food, energy and water shortages and the shift towards a hydrogen economy and renewables which require local production platforms for sustainability. Integrated PI-based technology is free of the burden of economies of scale which define the economics of centralized production. PI is therefore most useful in distributed–decentralized–local production.
Within PI, membranes play an important function because of the reduction of diffusion pathways for mass transfer as well as due to their selectivity and catalytic activity. This special issue will summarize the latest developments in membrane based PI across all disciplines in order to define the underlying mechanisms and cross-fertilization. We invite contributors to submit original research papers in membrane based process intensification in chemical, biochemical, biological, agricultural, environmental, energy conversion technologies covering separations, reactors, catalysis, combustion processes dealing with products such as chemicals, fine chemicals or resources such as water, air and solar radiation. The scope of the papers ranges from the existing polymeric, metallic, ceramic or composite membrane systems in process intensification to novel membranes specially tailored for process intensification.

Abstract: One of the most important results that can be obtained by the integration of reaction and membrane separation in a membrane reactor is a “process intensification”. In the present work, the requirements that the membrane must fulfill to pursue this goal are analyzed and discussed. The application of these principles is illustrated in a case study: the photocatalytic synthesis of vanillin, the most important flavor compound which is used in food, cosmetic and nutraceutical industries. In fact, the recovery from the photocatalytic reactor of the valuable vanillin by means of pervaporation or dialysis while it is produced allows a substantial enhancement of the yield, since its further oxidation is so prevented. The mechanisms of vanillin transport in the polymeric membrane material (polyether block amide) are investigated, since they ultimately affect the performances of the membrane reactor. The results show that unexpectedly the diffusion of vanillin takes place in presence of low concentration gradients of this permeating aldehyde, so that the process is limited by other phenomena.

Abstract: Fouling is by far the major challenge hampering the ability to enhance the performance of membrane separation operations increasingly being used in a wide range of applications (varying from biomedical engineering to wastewater treatment). Unfortunately, each field is developing its own way of solving the problem with limited interdisciplinary communication.
A comprehensive review of the various means available for mitigating the impact of fouling was therefore undertaken (in excess of 300 publications), and the results obtained were analyzed using fundamental mechanistic interpretation. This review revealed that although up to 8-fold increase in filtration flux was obtained by using the hydrodynamic means for mitigating fouling, an additional 5-fold enhancement can be achieved by combining this approach with feed coagulation/flocculation. This is mainly caused by the enhanced cake susceptibility to hydrodynamic shear (the sweep effect) but special attention must be given flocculating the constituents with the largest contribution to fouling.
