Book excerpt: Soil vapor extraction (SVE) systems are typically designed based on the results of a vadose zone pumping test (transient or steady state) using a pressure criteria to establish the zone of influence (ZOI). A common problem associated with pressure based SVE design is overestimating the ZOI of the extraction well. The vacuum criteria commonly used to establish the boundary of the ZOI results in large areas with very low pore velocities and thus long cleanup times. As a result, design strategies based upon critical pore gas velocity (CPGV) have increased in popularity. The CPGV is used in an effort to loosely incorporate the effects of mass transfer limitations into the design of SVE systems. Critical pore gas velocity designs use a minimum pore gas velocity rather than minimum vacuum to identify the extent of the treatment zone of an SVE system. The CPGV is typically much larger than the pore gas velocity at the perimeter of vacuum based (ZOI) designs resulting in shorter cleanup times. In this paper, we report the results of testing performed at the Savannah River Site (SRS) to determine the influence of a vapor extraction well based upon both a pressure and pore gas velocity design criteria. Results from this testing show that a SVE system designed based upon a CPGV is more robust and will have shorter cleanup times due to increased flow throughout the treatment zone. Pressure based SVE design may be appropriate in applications where soil gas containment is the primary objective; however, in cases where the capture and removal of contaminated soil gas is the primary objective, CPGV is a better design criteria.

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 2023-05-31 with total page 361 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: 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.

Book excerpt: Although soil vapor extraction (SVE) is well established as an effective method of removing volatile organic compounds from soil, the spatial extent of extraction influence is often poorly understood. Typically, the limit of a detectable vacuum response in vadose monitoring wells is used to define radius of influence without regard for the pneumatic conductivity, vacuum measurement limitations, or barometric pressure effects. Vapor flow conditions are often assumed to be confined, but even beneath surface pavement or clay layers, vertical leakance of air is usually a dominant influence.

This book was released on 1996 with total page 15 pages. Available in PDF, EPUB and Kindle. Book excerpt: Soil vapor extraction (SVE) is a proven tecnnology that can remove volatile organic compounds (VOCs) from the subsurface effectively if the conditions are favorable. However, most systems are designed by empirical methods or engineering judgement based on results of pilot tests. An attempt is made to develop a mathematical model for the technology so that optimal operating parameters can be obtained. The pressure distributions induced by multiple-well extractions are obtained by superimposing an existing analytical solution. Concentrations of VOCs as a function of time and space are obtained by numerical simulation of the migration and fate of VOC. The effectiveness of SVE systems using different operating parameters is evaluated on the basis of the quantity of contaminant removed. The developed mathematical model provides the necessary engineering design tools to evaluate different operation scenarios.
