CARBON DIOXIDE SEPARATION BY SELECTIVE PERMEATION.
Abstract
This report summarizes the result of a literature search, screening experiments, preliminary design and parametric study on removing carbon dioxide from air by selective permeation. Both microporous and polymeric materials were evaluated for this application. Silicone rubber was found to be the best material available for this application. Using this material, a preliminary design study indicated that an optimized system capable of recovering 2.5 pounds of 95% pure carbon dioxide per day from air containing 0.75% carbon dioxide, would require eleven stages, and 4.1 kilowatts of electrical power. Based upon these results it was concluded that a practical system can not be developed using currently available materials. A parametric study was performed to determine the material properties necessary for the development of a system that would be competitive with other techniques for carbon dioxide removal. It was concluded that the selectivity of the material must be more than three orders of magnitude higher; this is beyond current technology. (Author)
