Book Synopsis Effect of Surface Energy of Fibers on Coalescence Filtration by : Kavitha Moorthy
Download or read book Effect of Surface Energy of Fibers on Coalescence Filtration written by Kavitha Moorthy and published by . This book was released on 2007 with total page 108 pages. Available in PDF, EPUB and Kindle. Book excerpt: Water-oil emulsion separations are of importance to petrochemical industries. Water molecules of less than 100[mu] diameter are present as secondary emulsions. The presence of water reduces the efficiency of the fuel combustion, the water droplets can plug or interfere with performance of small orifices, and the water can dissolve polar compounds from the fuel and form corrosive materials such as sulfuric acid which can damage engine parts. Thus, fuel filtration extends the life of engine. Coalescence filters are efficient and effectual for the removal of secondary emulsions. The surface functionalization of fibers used to make coalescence filters can potentially provide cleaner air, and cleaner fuel with reduced water concentration. The solid surface energy of the fiber is a crucial factor in coalescence phenomena. The aim of this work is to eliminate these water molecules by development of filters made of glass with modified surface energy using coupling agents like silanes. Three coupling agents used in this work are 3-aminopropyltriethoxysilane (APTS), (2-(carboxymethylthio) ethyltrimethylsilane) (CES), and ((heptadecafluoro-1, 1, 2, 2-tetra-hydrodecyl) trichlorosilane) (FTS). The APTS functionalized surface having an intermediate surface energy of 65[millijoule]/m2 was found to be the most effective fiber for water-in-oil coalescence. Functionalized and unfunctionalized fiber filters were also tested for gas-liquid coalescence filtration. The experimental results showed an improvement in the performance of FTS coated glass filters compared to the untreated glass fiber filter. Intermediate wettability is commonly accepted to provide the best coalescing filter performance, but direct experimental evidence is scarce. This work experimentally confirms that intermediate wettability provides the best performance.

Book Synopsis Mixed Hydrophilic/hydrophobic Fiber Media for Liquid-liquid Coalescence by : Prashant Shashank Kulkarni
Download or read book Mixed Hydrophilic/hydrophobic Fiber Media for Liquid-liquid Coalescence written by Prashant Shashank Kulkarni and published by . This book was released on 2011 with total page 186 pages. Available in PDF, EPUB and Kindle. Book excerpt: Separation of liquid-liquid dispersions is important industrially and environmentally. Fibrous coalescing filters are used to separate liquid-liquid dispersions. Wettability of the fibers significantly influences the filter performance. The wettability of the filter media depends on surface properties of fiber materials and porosity of the filter medium. The wettability of filter media and interfacial tension of the liquid are the important factors in designing a coalescing filter media. It is generally accepted that the intermediate wettability gives best filter performance. However, the effect of wettability on filter performance is not well understood, especially at low interfacial tension liquids. In addition, wettability characterization techniques are not widely applied for fibrous filter media. The goal of this work is to study the effect of wettability on filter performance and by evaluating filter media of varying wetting properties. In this work, filter media were prepared by mixing hydrophilic and hydrophobic fibers to control the wettability and to improve the performance of the filter media. The mixing of fibers was achieved by designing filter media in different geometries. The different geometries developed and evaluated are mixed, layered and radially layered hydrophilic/hydrophobic fiber media. The wettability of the filter media was characterized using modified Washburn's equation and expressed as the Lipophilic to Hydrophilic (L/H) ratio. Water and Viscor-1487 oil were used as test liquids for the wettability characterization. The developed geometries resulted in variation in wettability. The filter media were tested in liquid-liquid coalescence experiments in which fine emulsion was generated by dispersing water droplets in the Viscor-1487 oil. The experimental results show that wettability of filter media can be controlled by constructing a media with different geometries and choosing a right composition of hydrophilic/hydrophobic fibers. The pressure drop of filter media was reduced with increase in L/H. The performance of filter hydrophilic/hydrophobic filter media was improved as compare to only glass fiber (hydrophilic) media. However, improvement in quality factor is mainly due to reduction in pressure drop. The best filter performance was achieved with layered and radially layered structures made of glass and polypropylene fibers having L/H between 2 to 10. The media developed with glass and electrospun polypropylene fibers shows significant improvement in separation efficiency but also increase in pressure drop. The results and approach of this work will be useful in designing and developing filter media for many industrial filtration applications.

Book Synopsis Improved Performance with Layer Orientation Incorporated Pleated Media on Coalescence Filtration by : Rahul Bharadwaj
Download or read book Improved Performance with Layer Orientation Incorporated Pleated Media on Coalescence Filtration written by Rahul Bharadwaj and published by . This book was released on 2010 with total page 224 pages. Available in PDF, EPUB and Kindle. Book excerpt: Experimental observations show fiber orientation and layer orientation in filter media effect the permeability and the separation efficiency of coalescing filters. The effects of fiber orientation have been studied by various industries including polymer, paper and textiles, to enhance their product lines. This has also been proven beneficial to the filtration industry because orientation of fibers can lead to lower pressure drop. The main objective of this work is to study the effects of layer orientations and test its performance. This technique is an alternative to using electric field for making oriented fiber media. It incorporates stacking micro fiber sheets at different angles (0,30,45,60 and 90). For capture of liquid droplets, the decrease in pressure drop obtained is offset by the decrease in capture efficiency, resulting in nearly constant quality factor regardless of fiber orientation. However, in coalescing filter media this method shows improvement in liquid drainage from the filter and can improve the quality factor from 20 to 60%. In coalescing filter media the fiber orientation can have an added benefit of reducing the liquid saturation in the filter media, which leads to an improved quality factor for the filter media and can be very useful in making self-cleaning filters. The stacking sheets can be extended to a pleated structure, which is relatively easier to construct from an industrial point of view. However, it is challenging to control the angle of the pleats during the construction of the media. Therefore varying the angle of the pleated structure with respect to the flow can surmount this problem. Another filter design is proposed which can mimic the angled pleated design by keeping the pleating angle constant (at zero degree) and changing the angle of the filter holder. Both designs have higher performance compared to a regular pleated media. Multiphase continuum equations are used to model the flow through the media to calculate the velocity and pressure profile through a pleated media to compare with the experimental results.
Book Synopsis Surface Modification of Polymeric Biomaterials by : Buddy D. Ratner
Download or read book Surface Modification of Polymeric Biomaterials written by Buddy D. Ratner and published by Springer Science & Business Media. This book was released on 2013-06-29 with total page 200 pages. Available in PDF, EPUB and Kindle. Book excerpt: Applications of synthetic materials in medicine date back over 4000 year2. The Egyptians used linen as sutures. In the Roman Empire, gold was used in dentistry. Perhaps even earlier, ivory and bone may have been used in the body by practitioners of the healing arts. The historical origins of modem biomaterials science are also hard to precisely trace, but many of the ideas that define biomaterials as we know them today evolved in the late 1950s and early 1960s. Surface modification technology has played a prominent role in biomaterials science, and has paralleled the evolution of the modem field. In a symposium organized by the Artifical Heart Program of the NIH National Heart Institute and the Artificial Kidney program of the NIH National Institute of Arthritis and Metabolic Diseases, held in Atlantic City, New Jersey, in 1968, there were already a number of presentations on surface modification. Surface characterization at that time included scanning electron microscopy, ellipsometry, contact angle methods, and infrared internal reflection methods.

Book Synopsis Improving Performance and Drainage of Coalescing Filters by : Shagufta Usman Patel
Download or read book Improving Performance and Drainage of Coalescing Filters written by Shagufta Usman Patel and published by . This book was released on 2010 with total page 226 pages. Available in PDF, EPUB and Kindle. Book excerpt: Pure air or gas is very critical to many industrial applications. Gas streams contain impurities in the form of solid and liquid aerosols of micron and submicron sizes. It is very important to remove these aerosols for improving the economy and reliability of industrial processes and equipment as well as protecting our health and environment. Among different filters being used, coalescing filters are effectively used to remove liquid aerosols from gas streams and hence has numerous industrial applications. The performance of the filter affects the economy of the process. A coalescing filter captures the oil droplets and the captured liquid typically drains from the filter by action of gravity. The saturation or hold-up of liquid in the filter constricts the gas flow, increases pressure drop, and increases the operating costs of the filter. The filter loaded with liquid droplet indicates limited filter life and needs to be replaced which increases the cost of process. Filter performance and filter life can be improved if the liquid saturation is reduced without reduction in capture efficiency. In this research work filter media are modified with drainage structures to reduce saturation and to reduce drag resistance. The media are tested in horizontal and vertical orientations to determine whether their orientation with gravity influences the performance. The experimental results show that with no drainage channels the media oriented with flow vertically downward operates the best whereas with drainage channels the horizontally oriented media had the best performance. The results also show filter geometries developed by embedding low surface energy woven drainage channels at 45 degree downward angles have the overall best performance. Adding nanofibers to improve the performance of the filter media is an effective way of improving filter media's capture efficiency with moderate increase in pressure drop. Nanofiber augmented filter media indicated higher pressure drop but when the drainage channels are incorporated in the filter, the increase in the pressure drop is significantly low. The pressure drop increase will be significant for a nanofiber augmented filter media without the drainage channels. Filter geometries developed by incorporating drainage channels at downward angles indicate significantly low pressure drop, the drainage channels create a path of lower resistance and hence maximum flow goes through the drainage channel improving the filter performance and drainage. This research work allows to develop cost effective filter geometries which will significantly increase filter performance as compared to the glass fiber filter media which are commonly used in the industry.
