Special Issue Information

Dear Colleagues,

Membranes have been widely used in fluid–fluid and fluid–solid separation processes in different fields (chemistry, physics, engineering, and medical sciences) depending on the nature/structure (ceramic or polymeric) and potential characteristics for industrial applications (microfiltration, ultrafiltration, nanofiltration, reverse osmosis) in, but are not limited to, water treatment, environment cleaning, energy storage and demand, and food, textile, and pharmaceutical processing. The separation processes of membranes involve many physical and chemical phenomena, such as heat and mass transfer, fluid flow, concentration polarization, fouling, and related phenomena. Therefore, it is important to understand the factors that affect the transport phenomena involved in the process separation of membranes. The aim is to maximize the selectivity performance (separation efficiency) for a specific treatment in terms of material, design, energy, cost, and regulations.

This Special Issue entitled “Transport Processes in Membranes: From Theory and Modeling to Industrial and Technological Applications” will present theoretical and experimental studies related to heat and mass transfer and fluid flow during the process of separation by membranes. The idea is to stimulate advanced research and emerging trends in this important topic.

As Guest Editors, we encourage authors to publish/submit their innovative experimental and theoretical/computational research as well as review papers related to membrane separation processes, with particular reference to transport processes, to this Special Issue. However, manuscripts with different focus, but related to separation processes in membranes, are welcome.

Wastewater from the oil industry can be considered a dangerous contaminant for the environment and needs to be treated before disposal or re-use. Currently, membrane separation is one of the most used technologies for the treatment of produced water. Therefore, the present work aims to study the process of separating oily water in a module equipped with a ceramic membrane, based on the Eulerian–Eulerian approach and the Shear-Stress Transport (SST k-ω) turbulence model, using the Ansys Fluent® 15.0. The hydrodynamic behavior of the water/oil mixture in the filtration module was evaluated under different conditions of the mass flow rate of the fluid mixture and oil concentration at the entrance, the diameter of the oil particles, and membrane permeability and porosity. It was found that an increase in the feed mass flow rate from 0.5 to 1.5 kg/s significantly influenced transmembrane pressure, that varied from 33.00 to 221.32 kPa. Besides, it was observed that the particle diameter and porosity of the membranes did not influence the performance of the filtration module; it was also verified that increasing the permeability of the membranes, from 3 × 10−15 to 3 × 10−13 m2, caused transmembrane pressure reduction of 22.77%. The greater the average oil concentration at the permeate (from 0.021 to 0.037 kg/m3) and concentrate (from 1.00 to 1.154 kg/m3) outlets, the higher the average flow rate of oil at the permeate outlets. These results showed that the filter separator has good potential for water/oil separation. Full article

Petroleum has been extracted from oil reservoirs using different techniques. This activity is accompanied for a large amount of water and sometimes mixed with gas. This produced water has a high oil concentration and other toxic chemical compounds, thus, it must be treated to be reused or released to environment according to environmental protection regulations. Currently, ceramic membrane technology has been employed in the wastewater treatment, due to its high benefit–cost ratio. In this sense, this work aims to study the oil–water mixture separation process using a new configuration of tubular ceramic membrane module by computational fluid dynamic (ANSYS Fluent software). The proposed model is composed of mass and linear momentum conservation equations coupled to Darcy’s law and SST k-ω turbulence model. Results of the volumetric fraction, pressure, and velocity distribution of the oil and water phases are presented and discussed. The results indicated that the proposed model and new device both have great potential to be used on the water/oil separation process and that the transmembrane pressure remains constant in the axial direction and decreases radially through the membranes, indicating an efficient system that favors the transport of clean water and oil retention.
