System and method for adsorbing contaminants and regenerating the
adsorber
摘要:
A system for adsorbing a plurality of contaminants from a workstream composed of a first stage open-ended activated carbon monolith adsorber, a second stage open ended activated carbon monolith adsorber downstream of the first stage. The first stage activated carbon has an average pore size that is larger than the average pore size of the second stage activated carbon. A method for removing more than one contaminant from a workstream which involves passing a workstream containing more than one contaminant through a first open ended activated carbon monolith adsorber having a pore size suitable for adsorbing the major portion of the larger size contaminant and for allowing the smaller size contaminant to pass through the monolith, to cause adsorption of the major portion of the larger size contaminant by the activated carbon, while allowing the smaller size contaminant to pass through the first monolith, and thereafter passing the effluent from the first adsorber through a second open ended activated carbon monolith adsorber having a pore size suitable for adsorbing the smaller size contaminant to cause adsorption of the major portion of the smaller size contaminant by the second monolith activated carbon. The adsorbed contaminants can then be desorbed by passing a regenerating stream(s) through the respective monoliths.
