Afrl-rx-ty-tp-2010-0067 Performance Assessment of Bench-scale Electrothermal Swing Adsorption Protective Filter Systems
نویسندگان
چکیده
Electrothermal Swing Adsorption (ESA), or Joule-Effect heating of adsorbents in a cyclic adsorption process, is an energy-efficient technology on which to base a regenerative protective filter system. In an attempt to define the performance envelope of ESA systems, we evaluated three different ESA media: Activated carbon fiber cloth (ACFC), Carbon Fiber Composite Molecular Sieve (CFCMS), and MicrolithTM (a trademark of PCI, Inc., a zeolite-coated wire mesh). Bench-scale systems based on these media were constructed and evaluated. Coincidentally, the three systems used different reactor morphologies: baghouse, axial flow, and radial flow. The performance of these systems in terms of removal efficiency, power consumption, weight, cube, and operability is discussed.

Activated carbon fiber cloth electrothermal swing adsorption system.
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 th...
متن کاملSteady-state and dynamic desorption of organic vapor from activated carbon with electrothermal swing adsorption.
A new method to achieve steady-state and dynamic-tracking desorption of organic compounds from activated carbon was developed and tested with a bench-scale system. Activated carbon fiber cloth (ACFC) was used to adsorb methyl ethyl ketone (MEK) from air streams. Direct electrothermal heating was then used to desorb the vapor to generate select vapor concentrations at 500 ppmv and 5000 ppmv in a...

Backgrounds and Objectives: Volatile organic compounds (VOCs) are one of the common groups of contaminants encountered in the industrial activities, emitted through air stream into the atmosphere. To prevent the human and environmental health from the adverse effects of VOCs, air streams containing VOCs need to be treated before discharging to environment. This study was aimed at investigating ...
