摘要
Methods for desorbing volatile organic compounds (VOCs) from beaded activated carbon (BAC) that is loaded with VOCs, during the VOC abatement process using the fluidized carbon bead system include transferring the loaded BAC in an adsorber to a desorber, where a stream of organic solvent passes over the BAC to dissolve at least a portion of the adsorbed VOCs into the organic solvent to regenerate BAC. The regenerated BAC is returned to the adsorber. The organic solvent containing dissolved VOCs may be transferred to a distiller to separate the organic solvents from the dissolved VOCs and may be reused as the organic solvent in the desorber.
