Book Description
Capture and recovery of hazardous air pollutants (HAPs) and volatile organic compounds (VOCs) from gas streams using physical adsorption onto activated carbon fiber cloth (ACFC) is demonstrated on the bench-scale. This system is regenerated electrothermally, by passing an electric current directly through the ACFC. The adsorbate desorbs from the ACFC, rapidly condenses on the inside walls of the adsorber, and then drains from the adsorber as a pure liquid. Rapid electrothermal desorption exhibits such unique characteristics as extremely low purge gas flow rate, rapid rate of ADFC heating, rapid mass transfer kinetics inherent to ACFC, and in-vessel condensation. An existing system was scaled up 500%, and the new system was modeled using material and energy balances. ... These results allow the modeling of electrothermal desorption of organic vapors from gas streams with in-vessel condensation to optimize operating conditions of the system during regeneration of the adsorbent.

Book Description
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.

Book Description
Regenerative filtration based upon activated carbon cloth (ACFC) and direct ohmic heating is being investigated for both environmental and military applications. Although these Electrothermal Swing Adsorption (ESA) systems have been demonstrated at the bench and pilot scale, further development is needed for scale up and manufacturability. This project consisted of the design, manufacture and testing of a tenth scale Vapor Phase Removal and Recovery System (VaPRRS) filter prototype. The adsorption filter created during this project would function as the primary adsorption filter in a VaPRRS used during the painting of United States Air Force aircraft wheel wells. The VaPRRS is expected to replace the single use filters currently used in this application and provide performance and overall system cost benefits.

Book Description
Activated-carbon fiber-cloth (ACFC) has been investigated as an alternative adsorbent to remove volatile organic compounds (VOCs) and hazardous air pollutants (HAPs) from gas streams when compared to conventional granular activated carbons (GACs). ACFC has up to twice the adsorption capacity of GAC and is more suited to electrothermal regeneration.

Book Description
This monograph consists of manuscripts submitted by invited speakers who participated in the symposium "Industrial Environmental Chemistry: Waste Minimization in Industrial Processes and Remediation of Hazardous Waste," held March 24-26, 1992, at Texas A&M University. This meeting was the tenth annual international symposium sponsored by the Texas A&M Industry-University Cooperative Chemistry Program (IUCCP). The program was developed by an academic-industrial steering committee consisting of the co-chairmen, Professors Donald T. Sawyer and Arthur E. Martell of the Texas A&M University Chemistry Department, and members appointed by the sponsoring companies: Bernie A. Allen, Jr., Dow Chemical USA; Kirk W. Brown, Texas A&M University; Abraham Clearfield, Texas A&M University; Greg Leyes, Monsanto Company; Jay Warner, Hoechst-Celanese Corporation; Paul M. Zakriski, BF Goodrich Company; and Emile A. Schweikert, Texas A&M University (IUCCP Coordinator). The subject of this conference reflects the interest that has developed in academic institutions and industry for technological solutions to environmental contamination by industrial wastes. Progress is most likely with strategies that minimize waste production from industrial processes. Clearly the key to the protection and preservation of the environment will be through R&D that optimizes chemical processes to minimize or eliminate waste streams. Eleven of the papers are directed to waste minimization. An additional ten papers discuss chemical and biological remediation strategies for hazardous wastes that contaminate soils, sludges, and water.
