This book was released on 1999 with total page 39 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Clean Air Act Amendments of 1990 mandate the reduction of emissions of hazardous air pollutants (HAP). Activated carbon fiber-cloth (ACFC) offers promise as a superior adsorbent to remove and recover organic HAP from gas streams. This study designed, built, and tested a second-generation system with an improved adsorber using methyl ethyl ketone (MEK) as the organic pollutant. Total flow rate of the bench-scale system was 5 Lpm with the gas stream containing 1000 ppmv MEK. Breakthrough times ranged between 11.9 and 12.9 hr. Throughput ratios of 86.9 percent were achieved. Electrothermal regeneration times were approximately 1 hr at 100W. It was shown that increasing the adsorption bed's dry-bulb temperature by 10 degrees C can cut adverse effects of treating high humidity gas streams in half. The system was automated to demonstrate continuous MEK adsorption, desorption, condensation, and recovery. Overall removal efficiency during continuous operation was 99.9 percent by mass. The study's preliminary design and cost analysis for a pilot-scale system estimates a cost of $60,000 for a flow rate of 0.5 m3/min and a concentration of 1000 ppmv. An economic analysis of a proposed full-scale system shows that a process recovery cost of $2/kg of MEK is achievable.

This book was released on 1998 with total page 65 pages. Available in PDF, EPUB and Kindle. Book excerpt: Abatement of toxic volatile organic compounds (TVOCs) emitted to the atmosphere has become a concern because of the magnitude of the emissions and their potential health effects to humans and deleterious effects to the environment. New control technologies are being developed to separate and remove those toxic compounds from gas streams for reuse of the TVOCs in the process that generated them. This project evaluated the ability of an activated carbon fiber cloth (ACFC) adsorption, electrothermal desorption, cryogenic-condensation system to remove 10 cu cm/min containing 1000 ppmv of methyl ethyl ketone (MEK) or toluene from air streams that are dry or at 90 percent relative humidity. Results indicate that MEK and toluene are readily adsorbed from the carrier gas streams with the ACFC adsorber. Electrothermal desorption is also effective at desorbing the TVOCs and water from the ACFC. Cryogenic condensation is also effective for the dry MEK and toluene desorption conditions. Economic analysis shows that capitol costs for a conventional thermal swing GAC adsorption system will be 1.7 times greater than this system for the toluene dry air stream. The MEK recovery credit will be approximately four times greater than the annual operating costs for the MEK dry air stream.

Available in PDF, EPUB and Kindle. Book excerpt: The growth and development witnessed today in modern science, engineering, and technology owes a heavy debt to the rare, refractory, and reactive metals group, of which niobium is a member. Extractive Metallurgy of Niobium presents a vivid account of the metal through its comprehensive discussions of properties and applications, resources and resource processing, chemical processing and compound preparation, metal extraction, and refining and consolidation. Typical flow sheets adopted in some leading niobium-producing countries for the beneficiation of various niobium sources are presented, and various chemical processes for producing pure forms of niobium intermediates such as chloride, fluoride, and oxide are discussed. The book also explains how to liberate the metal from its intermediates and describes the physico-chemical principles involved. It is an excellent reference for chemical metallurgists, hydrometallurgists, extraction and process metallurgists, and minerals processors. It is also valuable to a wide variety of scientists, engineers, technologists, and students interested in the topic.

Available in PDF, EPUB and Kindle. Book excerpt: Organic solvents represent a class of compounds whose utility is central to industrial and academic chemistry. The impact of solvents in everyday products such as paints, surface coatings, adhesives, pharmaceuticals and cleaning products is enormous, and there is therefore much interest in their use. This volume is divided into two parts. Part 1 provides and authoritative review of the science and technology of solvents and related issues. The topics covered are solvency and its measurement, flammability, health and toxicology, environmental issues, legislative information, transport, storage, recovery and disposal, and a review of solvent applications. Part 2 provides reliable, up- to-date data, based on information provided by manufacturers and suppliers and is presented as a database of over 350 solvent products, subdivided by solvent group. The data are also presented in key parameter tables, covering boiling points, melting points, evaporation information, vapor pressure, flash points, solubility parameters, auto ignition temperatures, and names and addresses of manufacturers, with trade names. In recent years there has been increased interest in health and safety, environmental issues and aspects of the legislative control of chemicals, including solvents, and the choice of a given solvent has therefore become more complex. The Directory of Solvents aims to provide in one place a broad spread of physico-chemical data, together with transport, safety, environmental and classification information provided by major European and U.S. suppliers and manufacturers of industrial organic solvents.

Available in PDF, EPUB and Kindle. Book excerpt: MUNICIPAL SOLID WASTE TO ENERGY CONVERSION PROCESSES A TECHNICAL AND ECONOMIC REVIEW OF EMERGING WASTE DISPOSAL TECHNOLOGIES Intended for a wide audience ranging from engineers and academics to decision-makers in both the public and private sectors, Municipal Solid Waste to Energy Conversion Processes: Economic, Technical, and Renewable Comparisons reviews the current state of the solid waste disposal industry. It details how the proven plasma gasification technology can be used to manage Municipal Solid Waste (MSW) and to generate energy and revenues for local communities in an environmentally safe manner with essentially no wastes. Beginning with an introduction to pyrolysis/gasification and combustion technologies, the book provides many case studies on various waste-to-energy (WTE) technologies and creates an economic and technical baseline from which all current and emerging WTE technologies could be compared and evaluated. Topics include: Pyrolysis/gasification technology, the most suitable and economically viable approach for the management of wastes Combustion technology Other renewable energy resources including wind and hydroelectric energy Plasma economics Cash flows as a revenue source for waste solids-to-energy management Plant operations, with an independent case study of Eco-Valley plant in Utashinai, Japan Extensive case studies of garbage to liquid fuels, wastes to electricity, and wastes to power ethanol plants illustrate how currently generated MSW and past wastes in landfills can be processed with proven plasma gasification technology to eliminate air and water pollution from landfills.
