Performance Assessment of Bench-Scale Electrothermal Swing Adsorption Protective Filter Systems

摘要

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 Microlith (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.
