This book was released on 2012-12-06 with total page 341 pages. Available in PDF, EPUB and Kindle. Book excerpt: Masters Theses in the Pure and Applied Sciences was first conceived, published, and disseminated by the Center for Information and Numerical Data Analysis and Synthesis (CINDAS)* at Purdue University in 1957, starting its coverage of theses with the academic year 1955. Beginning with Volume 13, the printing and dis semination phases of the activity were transferred to University Microfilms/Xerox of Ann Arbor, Michigan, with the thought that such an arrangement would be more beneficial to the academic and general scientific and technical community. After five years of this jOint undertaking we had concluded that it was in the interest of all concerned if the printing and distribution of the volumes were handled by an international publishing house to assure improved service and broader dissemination. Hence, starting with Volume 18, Masters Theses in the Pure and Applied Sciences has been disseminated on a worldwide basis by Plenum Publishing Corporation of New York, and in the same year the coverage was broadened to include Canadian universities. All back issues can also be ordered from Plenum. We have reported in Volume 40 (thesis year 1995) a total of 10,746 thesis titles from 19 Canadian and 144 United States universities. We are sure that this broader base for these titles reported will greatly enhance the value of this impor tant annual reference work. While Volume 40 reports theses submitted in 1995, on occasion, certain uni versities do report theses submitted in previous years but not reported at the time.
Download or read book Design of Remediation Systems written by Jimmy H. C. Wong and published by CRC Press. This book was released on 2020-08-18 with total page 286 pages. Available in PDF, EPUB and Kindle. Book excerpt: While numerous books are available on remediation systems, this is the first work to document and explain in full the design aspects of the subject. Based on sound engineering principles and practical construction considerations, this text explains the entire process of remediation design, from assessment to completion, and provides engineers with the tools they need to conduct a pilot test, apply the results, and design a practical, efficient system. Design of Remediation Systems first establishes the underlying principles behind each technology, then outlines the standard procedures for designing a system. This comprehensive manual explains feasibility and pilot tests, data evaluation, design considerations and parameters, calculations and equations, and construction aspects of the system. Also featured are discussions of the operation and maintenance of systems, and analysis of current trends, such as combining soil vapor extraction with air sparging. Detailed case study examples are included in each chapter. The book considers petroleum hydrocarbons as the primary contaminant, but the principles and procedures can be applied to a wide range of other contaminants. This hands-on text/reference presents a complete picture of remediation system design for engineers, students, and scientists. No other single work offers the thorough coverage of this critical aspect of remediation.

Download or read book Soil Vapor Extraction Using Radio Frequency Heating written by Donald F. Lowe and published by CRC Press. This book was released on 1999-12-06 with total page 374 pages. Available in PDF, EPUB and Kindle. Book excerpt: One of the most widely used techniques for treating soils contaminated with volatile organic compounds, soil vapor extraction (SVE) can also be applied to semi-volatile organic compounds (SVOCs) if the soil is heated, by applying electromagnetic energy in the radio frequency (FR) range, to increase the vapor pressure of the contaminants. Although RF-SVE systems used in previous field demonstrations have had varying degrees of success, questions remain concerning its viability and cost-effectiveness. Soil Vapor Extraction Using Radio Frequency Heating: Resource Manual and Technology Demonstration covers detailed scientific and engineering information that answers these questions. The book includes the necessary databases, equations, and example calculations for RF heating. The theoretical and practical information included will facilitate future testing of RF-SVE treatment of soils. Additionally, the book provides information for a full-scale engineering design of potential RF-SVE applications. The authors use this information to examine predicted performance, magnitude of costs, and modifications to the design that may decrease cost. Soil Vapor Extraction Using Radio Frequency Heating: Resource Manual and Technology Demonstration gives an economic analysis of this innovative technology and considers other possible applications for it.

Available in PDF, EPUB and Kindle. Book excerpt: This report provides an engineering analysis of, and status report on, selected enhancements for soil vapor extraction (SVE) treatment technologies. The report is intended to assist project managers considering an SVE treatment system by providing them with an up-to-date status of enhancement technologies; an evaluation of each technology's applicability to various site conditions; a presentation of cost and performance information; a list of vendors specializing in the technologies; a discussion of relative strengths and limitations of the technologies; recommendations to keep in mind when considering the enhancements; and a compilation of references. The performance of an SVE system depends on properties of both the contaminants and the soil. SVE is generally applicable to compounds with a vapor pressure of greater than 1 millimeter of mercury at 20EC and a Henry s Law constant of greater than 100 atmospheres per mole fraction. SVE is most effective at sites with relatively permeable contaminated soil and with saturated hydraulic conductivities of greater than 1 x 10 or 1 x 10 centimeter per second (cm/s). SVE by itself does not effectively remove contaminants -3 -2 in saturated soil. However, SVE can be used as an integral part of some treatment schemes that treat both groundwater and the overlying vadose zone. Enhancement technologies should be considered when contaminant or soil characteristics limit the effectiveness of SVE or when contaminants are present in saturated soil. The five enhancement technologies covered in this report are as follows and are described in the following subsections: * Air Sparging * Dual-phase Extraction * Directional Drilling * Pneumatic and Hydraulic Fracturing * Thermal Enhancement.

Download or read book Soil Vapor Extraction Enhanced with Prefabricated Vertical Drains written by Omaira M. Collazos and published by . This book was released on 2003 with total page 410 pages. Available in PDF, EPUB and Kindle. Book excerpt: Soil vapor extraction (SVE) is an effective and cost efficient method of removing volatile organic compounds (VOCs) and petroleum hydrocarbons from unsaturated soils. However, soil vapor extraction becomes ineffective in soils with low gas permeability, for example soils with air permeabilities less than 1 Darcy (e.g. silty sand or silt). Prefabricated vertical drains (PVDs) have been used for dewatering fine-grained soils for more than 20 years. For the last five years, PV drains have been used for soil flushing applications in order to remove contaminants below the ground water table. Incorporating PV drains in an SVE system can extend the effectiveness of SVE to lower permeability soils by shortening the air flow-paths and ultimately expediting contaminant removal. An advantage of using PV drains in place of conventional SVE wells is that they can be installed relatively inexpensively. The objective of the work described herein was to effectively incorporate PV drains into a SVE remediation system and to demonstrate a PV drain enhanced SVE system at full-scale. The results of the laboratory tests showed that the equivalent well diameter does not significantly influence the calculated air permeability and that Darcy's law is valid for the range of conditions tested (flow rates of 787-2600 cm 3 /s). In addition, factors contributing to the difference between the theoretical and measured pressure heads were analyzed. It is concluded that the air flow rate and the ratio of the radius to radius of influence (r/R I) were the most significant parameters. Results of the field demonstration indicated that the radius of influence for the PV drains was less than 1.8 m in the clayey soils at the site and the PV drain system site captured methane gas migrating laterally from a landfill. The concentration in the monitoring probe was reduced from 9 percent to less than 1 percent methane and did not recover after 7 days with no further extraction. The findings from this program will facilitate the design of field PVD-SVE systems in terms by providing insight into the optimal spacing between PV drains, the radius of influence of the wells and the flow rates to be used to capture and extract gas phase contaminants.
Download or read book Michigan Soil Vapor Extraction Remediation MISER Model written by Linda M. Abriola and published by . This book was released on 1997 with total page 4 pages. Available in PDF, EPUB and Kindle. Book excerpt: Soil vapor extraction (SVE) and bioventing (BV) are proven strategies for remediation of unsaturated zone soils. Mathematical models are powerful tools that can be used to integrate and quantify the interaction of physical, chemical, and biological processes occurring in field scale SVE/VB systems. This report describes the conceptual and mathematical formulation, numerical implementation, and application of a multiphase, multicomponent, biodegradation model designed to simulate physical, chemical, and biological interactions occurring in field scale SVE and BV systems. The model, the Michigan Soil Vapor Extraction Remediation Model (MISER), is two-dimensional and may be run in a cross-sectional or axisymmetric mode. Phase and constituent mass balance equations are discretized with a standard Galerkin finite element approach using linear triangular elements. A modular, set-iterative solution algorithm is employed. Features of the model include: the ability to simulate multiphase gas and aqueous fluid flow; the simulation of multicomponent transport processes, incorporation of rate-limited interphase mass transfer for volatilization and dissolution of an entrapped organic liquid, volatilization and sorption of aqueous phase constituents, and biophase update; and the simulation of multicomponent biodegradation kinetics and microbial population dynamics. A complete description of the computer code, implementation procedures, and example SVE and BV simulations is included.
