DEVICE FOR SEPARATING CO2 FROM FOSSIL-FUELED POWER PLANT EMISSIONS

摘要

A gas separation device (10) includes an inner conduit (14), and a concentri c outer conduit (18). An electrically conductive filter media (60), preferably a carbon fiber composite molecular sieve, is provided in the annular space between the inner conduit and the outer conduit. Gas flows through the inner conduit and the annular space between the inner conduit and the outer condui t, so as to contact the filter media. The filter media preferentially adsorbs a t least one constituent of the gas stream. The filter media is regenerated by causing an electric current to flow through the filter media. The inner conduit and outer conduit are preferably electrically conductive whereby the regeneration of the filter media can be electrically stimulated. The inventi on is particularly useful for the removal of CO2 from the exhaust gases of foss il- fueled power plants.
