Available in PDF, EPUB and Kindle. Book excerpt: A program was conducted to determine the feasibility of the concept of using hydrophilic membranes for oil-water separations and to evaluate conceptually its practical applicability for shipboard use. Twenty candidate membranes were screened with respect to oil rejection capabilities and product water flux. The most promising membrane, a surface-hydrolyzed cellulose acetate, showed essentially complete oil rejection and was further studied to evaluate its performance under various operating conditions. The effects of input feed temperature flow rate, salt concentrations, applied pressure, and type and concentration of oil contaminants were determined. Several simple cleaning procedures were investigated in an effort to restore product water flux after fouling of the membrane surface with oil. Preliminary designs for low-pressure systems to produce 100 and 1000 gpm of oil-free product were developed, based on a spiral-wound modular system. A summary of limitations and constraints of a proposed 100-gpm system for shipboard application is presented, along with spatial, weight, and energy requirements and economic factors for such a system.

Download or read book Fundamental Study of Hydrophobic Microporous Membrane Contactors for the Recovery of Insoluble Oil from Oil water Mixtures written by Aurore Yvonne Joelle Mercelat and published by . This book was released on 2016 with total page 336 pages. Available in PDF, EPUB and Kindle. Book excerpt: Insoluble oil and water mixtures occur in many industries such as food, metallurgical, or biofuel production. In particular, as we strive to meet global energy demands, the associated risks and waste management of the oil and gas industry must be addressed. Technologies capable of separating oil and water efficiently are needed for the treatment of highly variable oil and gas streams such as produced and flowback waters or oil spills. The goal of this doctoral work was to advance the understanding of a membrane contactor process for the recovery of insoluble oil from water. The hydrophobic hollow fiber membrane had been successfully tested in our laboratories for oil recovery from algae slurries. However, a thorough study to understand the fundamental mechanisms of the separation process was necessary for engineering design and process optimization. First, pure oil experiments were performed to define baseline performance attainable with the studied membrane contactors. Then, oil-water separation experiments were conducted to quantify the effect of key operating parameters. Two relevant ranges of oil feed concentration were identified. For high oil feed concentration, increases in transmembrane pressure and influent flow rate were confirmed to increase oil flux, while higher viscosity lowered oil permeation across the fiber walls. However, an important finding was that, for dilute mixtures, decreases in transmembrane pressure and higher viscosity increased oil permeation. The results of this research support the conclusion that oil separation within the particular geometry and design of the membrane contactor is due to both internal coalescence of oil droplets and selective permeation of oil over water. The stability of an oil film on the fibers was critical to enhance effective surface area of the membrane contactor. In addition, the technology showed great promise for long-term high oil removal with no signs of viscous fouling as often observed in hydrophilic membranes. Finally, a model describing the process was developed and can be used as a guideline for membrane sizing and process engineering design.
