The Air Force is using the air stripping process to remove a variety of volatile organic contaminants from groundwater. Vapor-phase granular activated carbon (GAC) has proven successful in treating the contaminated air stream emanating from air stripping columns. but conventional regeneration methods are expensive, require transfer of the carbon. and degrade the carbon. The objective of this experimental program was to determine the feasibility of using electrically-heated processes for the in-place regeneration of vapor-phase GAC. Two processes were considered, namely microwave heating and electric resistance heating using the carbon itself as the resistance. The microwave heating equipment used gave nonuniform heating over the length of the carbon column and was not pursued further. Electric resistance, or Rintoul, heating is a commercially proven process that has been applied to the high-temperature regeneration of liquid-phase GAC in special purpose furnaces. The experimental program demonstrated that the Rintoul process can be efficiently applied to low-temperature, low energy, in-place regeneration of vapor-phase GAO. Repeated loading and regeneration of the carbon column showed no loss of adsorption capacity. Two methods of collecting TCE in a concentrated form were also successfully tested. Both processes involved recovery of the TCE in a condensate. jg.

Download Activated Carbon Surfaces in Environmental Remediation Book in PDF, ePub and Kindle
Activated Carbon Surfaces in Environmental Remediation provides a comprehensive summary of the environmental applications of activated carbons. In order to understand the removal of contaminants and pollutants on activated carbons, the theoretical bases of adsorption phenomena are discussed. The effects of pore structure and surface chemistry are also addressed from both science and engineering perspectives. Each chapter provides examples of real applications with an emphasis on the role of the carbon surface in adsorption or reactive adsorption. The practical aspects addressed in this book cover the broad spectrum of applications from air and water cleaning and energy storage to warfare gas removal and biomedical applications. This book can serve as a handbook or reference book for graduate students, researchers and practitioners with an interest in filtration, water treatment, adsorbents and air cleaning, in addition to environmental policies and regulations. Addresses fundamental carbon science and how it relates to applications of carbon surfaces Describes the broad spectrum of activated carbon applications in environmental remediation Serves as a handbook or reference book for graduate students, researchers and practitioners in the field

Download A Novel Process for the Regeneration of Carbon Book in PDF, ePub and Kindle
The application of a voltage across dry granular activated carbon, which has limited electrical conductivity, results in rapid heating of the carbon to high temperatures, i.e. resistive heating. The application of this method of heating to eluted carbon from a carbon-in-pulp (CIP) plant for the recovery of gold involves drying of the eluted carbon and the use of a novel resistive-heating furnace - the Rintoul furnace. This furnace incorporates the patented concept of a 'floating' or common neutral. The Council for Mineral Technology (Mintek) has been closely involved in the development of this method for the regeneration of carbon into a commercial process. This paper gives an account of the designing and testing, at Mintek, of a novel type of dryer using hot air, and describes various laboratory size resistive-heating furnaces and their operation. The results obtained from laboratory-scale and pilot-scale testwork on the regeneration of samples of eluted carbon from various CIP plants are presented and discussed, including the effects of temperature, time and the presence of steam on the degree of regeneration of these samples of eluted carbon. It is also shown that this furnace can be used to reactivate heavily contaminated industrial carbon and to further activate or upgrade carbon having low initial activity.
