This book was released on 2014 with total page 312 pages. Available in PDF, EPUB and Kindle. Book excerpt: Due to the increasing need for the ability to predict multicomponent adsorption, the development of the homogeneous surface diffusion model (HSDM) and pore surface diffusion model (PSDM) for multicomponent adsorption in batch and fixed-bed reactors is presented. The models are solved using the method of orthogonal collocation and verified against simplified models. Two multicomponent laboratory column studies are satisfactorily predicted using estimated mass transfer parameters and experimentally determined isotherm parameters. A sensitivity analysis is performed on the models to determine which input parameters have the greatest effect on batch and fixed-bed profiles. Process design considerations are presented which compare the number of bed volumes that can be treated for an adsorbate in a groundwater matrix to the maximum number of bed volumes that can be treated under equilibrium conditions and no mass transfer resistance. Calculations are given for a single adsorber, two adsorbers in series, and a single adsorber which incorporates backwashing.

Download or read book Two Dimensional Modelling of Volatile Organic Compounds Adsorption in a Fixed Bed Adsorber written by Dereje Tamiru Tefera and published by . This book was released on 2013 with total page 96 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this research two-dimensional mathematical models were developed to study adsorption of single component volatile organic compounds (VOCs) and competitive adsorption of n-component mixtures of VOCs from dilute gas streams in a fixed-bed adsorber. The models consist of the macroscopic mass, energy and momentum conservation equations and isotherm equations. Langmuir isotherm was used for single component VOC adsorption, while a new multicomponent isotherm model was derived to predict adsorption equilibria of VOCs mixture from single component isotherm data. The models were validated with experiments wherein deviation between measured and modeled data was quantified using the mean absolute relative error (MARE). The single component adsorption model predicted the breakthrough curves of the tested VOCs (acetone, benzene, toluene and 1, 2, 4-trimethylbenzene as well as the pressure drop and temperature during benzene adsorption with MRAE of 2.6, 11.8, and 0.8%, respectively. The model also showed very good sensitivity to the changes in operations variables such as temperature and superficial velocity of the carrier gas, channeling, and adsorbent particle size. The competitive adsorption model predicted the breakthrough profiles of binary and eight-component VOCs mixtures with 13 and 12%, MRAE respectively while that of the adsorbed amounts was 1 and 2%, respectively. These results indicate the accuracy of the models to simulate a fixed bed adsorber and their potential to be used for enhancing absorber design and optimization.

Download or read book Pressure Swing Adsorption written by Douglas M. Ruthven and published by John Wiley & Sons. This book was released on 1996-12-17 with total page 388 pages. Available in PDF, EPUB and Kindle. Book excerpt: Pressure Swing Adsorption is the first book that provides a coherent and concise summary of the underlying science and technology of pressure swing adsorption (PSA) processes at a level understandable to the practising engineer. PSA has achieved widespread commercial acceptance as the technology of choice for hydrogen purification, air separation and small scale air driers. However, PSA has numerous other actual and potential uses such as the recovery of methane from landfill gas, the production of carbon dioxide and other large scale applications. Since the design and optimization of a PSA process requires a somewhat mathematical model, two chapters of the book provide in-depth information on equilibrium theory and dynamic numerical simulation. However, this mathematical material will also help the general reader develop an understanding of the principles and strenghts and limitations of various approaches. PSA engineers, chemical engineers, environmental chemists, academicians and managers who must make informed decisions about purchasing costly PSA systems will find Pressure Swing Adsorption of particular value.

Download or read book Adsorption Technology in Water Treatment written by Eckhard Worch and published by Walter de Gruyter. This book was released on 2012-08-31 with total page 344 pages. Available in PDF, EPUB and Kindle. Book excerpt: Adsorption processes have played a central role in water treatment for many years but their importance is on the rise with the continuous discoveries of new micropollutants in the water cycle (pharmaceuticals for example). In addition to the classical application in drinking water treatment, other application fields are attracting increasing interest, such as wastewater treatment, groundwater remediation, treatment of landfill leachate, and so on. Based on the author's long-term experience in adsorption research, the scientific monograph treats the theoretical fundamentals of adsorption technology for water treatment from a practical perspective. It presents all the basics needed for experimental adsorption studies as well as for process modelling and adsorber design. Topics discussed in the monograph include: introduction into basic concepts and practical applications of adsorption processes; adsorbents and their characterisation, single and multi-solute adsorption equilibria, adsorption kinetics, adsorption dynamics in fixed-bed adsorbers and fixed-bed adsorber design, regeneration and reactivation of adsorbents, introduction into geosorption processes in bank filtration and groundwater recharge. According to the increasing importance of micropollutants in the water cycle, particular attention is paid to their competitive adsorption in presence of background organic matter. Clear illustrations, extensive literature references and a useful index make this work indispensible for both scientists and technicians involved in water treatment.
