Available in PDF, EPUB and Kindle. Book excerpt: The feasibility of utilizing the differential heating characteristics of microwave energy (MW) to aid in the chemical extraction and separation process of hazardous organic compounds from mixed hazardous waste, was studied at the INEL. The long-term objective of this work was to identify a practical method of separating or enhancing the separation process of organic hazardous waste components from mixed waste using microwave (MW) frequency radiation. Methods using MW energy for calcination, solidification, and drying of radioactive waste from nuclear facilities is becoming more attractive. In order to study the effectiveness of MW heating, samples of several organic chemicals simulating those which may be found at the Radioactive Waste Management Complex at the INEL were exposed to MW energy. Vapor collection and analysis was performed as a function of time, signal frequency, and MW power throughout the process. Signal frequencies ranging from 900 MHz t 8000 MHz were used. Although the signal frequency bandwidth of the selectivity was quite broad, for the material tested an indication of the frequency dependence in the selectivity of MW heating was given. Greater efficiency in terms of energy used and time required was observed. The relatively large electromagnetic field intensities generated at the resonant frequencies which were supported by the cavity sample holder demonstrated the use of cavity resonance to aid in the process of differential heating.

Available in PDF, EPUB and Kindle. Book excerpt: This book discusses the practical aspects of environmental technology organized into eight chapters relating to unit operations as follows: 1. Biological Technology2. Chemical Technology3. Containment and Barrier Technology4. Immobilization Technology5. Membrane Technology6. Physical Technology7. Radiation and Electrical Technology8. Thermal Destruction TechnologyTraditional technologies have been included, as well as those that can be considered innovative and emerging. The traditional approaches have been the most successful, as contractors are careful about bidding on some of the newer technologies. However, as regulatory requirements increase, markets will open for the innovative and emerging processes. There will be increasing pressure to break down complex waste streams, with each subsequent stream demanding separate treatment. In addition, a number of technologies have been developed by combining processes directly, or in a treatment train, and these developments are expected to assume increasing importance. However, such concerns as uncertainties due to liability, regulatory approval, price competition, and client approval have limited the application of some of these newer technologies.

This book was released on 1995-09-16 with total page 450 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume updates and combines two National Academy Press bestsellers--Prudent Practices for Handling Hazardous Chemicals in Laboratories and Prudent Practices for Disposal of Chemicals from Laboratories--which have served for more than a decade as leading sources of chemical safety guidelines for the laboratory. Developed by experts from academia and industry, with specialties in such areas as chemical sciences, pollution prevention, and laboratory safety, Prudent Practices for Safety in Laboratories provides step-by-step planning procedures for handling, storage, and disposal of chemicals. The volume explores the current culture of laboratory safety and provides an updated guide to federal regulations. Organized around a recommended workflow protocol for experiments, the book offers prudent practices designed to promote safety and it includes practical information on assessing hazards, managing chemicals, disposing of wastes, and more. Prudent Practices for Safety in Laboratories is essential reading for people working with laboratory chemicals: research chemists, technicians, safety officers, chemistry educators, and students.

Download or read book Microwave Treatment of Organic Contaminated Soil written by Suning Fan and published by . This book was released on 1989 with total page 160 pages. Available in PDF, EPUB and Kindle. Book excerpt: The development of microwave technology to treat hazardous wastes has been in progress at NJIT for the past three years. The initial stages of this program have focused on determining the' breadth of hazardous waste problems that are amenable to microwave technology applications. Benchscale studies have shown the following processes are technically possible: a. It is possible to steam strip organic volatiles from soil; b. Volatiles can be destroyed by impact upon lossy so lids c. Heavy metal ions can be immobilized in soil; d. It is possible to regenerate GAC on-site. e. It is possible to pyrolyze polyarmotic compounds in soil in-site, and, thereby, effect decontamination. In this thesis, it has been shown that a relatively nonvolatile compound like naphthalene can be steam-stripped from soil; that the incident microwave energy penetrates the soil; that for volatile compounds are difficult to quantify effects; that in a comparison of microwave to incineration based upon economic and other considerations. It is concluded that microwave can play an potentially significant role in the clean up at contaminated soil.

This book was released on 2013-06-29 with total page 261 pages. Available in PDF, EPUB and Kindle. Book excerpt: It is generally acknowledged today that the most effective strategy for toxic and hazardous waste management is: reduction, reuse and recycle. However, to date most of the activity has been in treatment technologies. This book focuses on recent technological issues commercially available or in various stages of implementation. Developments in the U.S. and Europe in the area of waste management policy and regulation are also examined since management and remediation have usually been conducted in response to regulatory requirements. This book serves as a state of the art resource on technologies and methodologies for the environmental protection manager involved in decisions concerning the management of toxic and hazardous waste.
