Solvent-regenerated activated carbon

Abstract

This report summarizes the results of a University/Industry research project, sponsored by the New York State Energy Research and Development Authority and Fluids Design Corporation. The experimental work was performed by the Department of Chemical Engineering at Rensselaer Polytechnic Instltute under the supervision of Dr. E. Bruce Nauman. The work was performed under subcontract to Fluids Design Corporation. The research project studied the solvent regeneration of actlvated carbon. Activated carbon was used to remove trace organics from aqueous streams, then regenerated by desorbing the adsorbates with organic solvents. The project included a survey of the potential applications in New York State industries, fundamental research on the adsorption/desorption phenomena, and design of a full-scale process. The economics of the full-scale process were evaluated and compared to alternate available technologies. The result of this work is a versatile process with attractive economics. A wide range of adsorbates and solvents were found to be acceptable for this process. The design methodologies are developed and the techniques for evaluating anew application are delineated.
