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.

An existing system was scaled up 500%, and the new system was modeled using material and energy balances. Adsorption isotherms using methyl ethyl ketone (MEK) and ACFC were obtained while electricity passed through the ACFC and at temperatures above MEK's boiling point. These isotherms agreed within 7% to Dubinin-Radushkevich modeled isotherms that were extrapolated from independently determined gravimetric measurements obtained at l...

Steady-State and Dynamic Desorption of Organic Vapor from Activated Carbon with Electrothermal Swing Adsorption

“…The electrothermal/microwave swing adsorption-recovery systems (ESA-R/MSA-R) remove organic vapors from gas streams with ACFC and recover the vapors as liquids with electrothermal/microwave regeneration of the ACFC with rapid in-vessel condensation of the organic vapors (8,9,15,16). This approach promotes recovery of the organic vapors as a liquid and helps to provide a more sustainable technology.…”

“…An energy balance for the control volume around both of the ACFC cartridges and fittings was developed based on Sullivan et al's work (9) to calculate the energy applied to the cartridges (Q e,c) during the regeneration cycles (eq 4). The energy balance considered the (1) specific heats of the adsorbent, adsorbed MEK, cartridges' fittings, and air; (2) convective heat transfer; (3) radiative heat transfer; and (4) isosteric heat of adsorption of MEK ( Table 1).…”

Development and Environmental Applications of Activated Carbon Cloths

“…The capture and recovery of HAPs and VOCs from gas streams using physical adsorption onto activated carbon fiber cloth on the bench scale was demonstrated by Sullivan et al [175]. Adsorption of methyl ethyl ketone (MEK) vapor from air streams onto the same aforementioned ACC from American Kynol Inc. was particularly investigated (Table 3).…”

Multiphysics modeling of electric-swing adsorption system with in-vessel condensation

“…Electric (or electrothermal) swing adsorption (ESA) is a relatively new name (Yu et al 2007;Sullivan et al 2004a) for an essentially temperature-swing adsorption (TSA) cycle in which the adsorbent material is heated by passing electric current through it (owing to Joule effect). The idea about regeneration of used adsorbent beds by direct heating by electric current was first published in the 1970s (Fabuss and Dubois 1970).…”

“…Most applications of electrothermal desorption have been based on fibrous activated carbon materials (Petkovska et al 1991;Rood et al 2002;Sullivan et al 2001Sullivan et al , 2004aSullivan et al , 2004bLe Cloirec 2004, 2006;Moon and Shim 2006;Luo et al 2006), although granular activated carbons (Snyder and Leesch 2001;Sushchev et al 2002;Luo et al 2006) and, recently, carbon monoliths (Luo et al 2006;Yu et al 2002Yu et al , 2007, have also been used.…”
