METHOD OF SEPARING CARBON DIOXIDE USING ACTIVE CARBON FIBER

摘要

PURPOSE: Provided is a method for adsorbing and separating carbon dioxide from flue gas by using activated carbon fiber in the pressure swing adsorption (PSA) so as to obtain high purity carbon dioxide massively. CONSTITUTION: The method comprises the steps of packing activated carbon dioxide in a column in a packing density of 0.5-0.7; introducing flue gas to be treated in the column and then compressing at an adsorbing pressure of 5 to 6atm for 80-120sec; supplying the flue gas maintaining 5-6atm of adsorbing pressure at a supply rate of 2000-4000cc/min for 300-360sec so as to adsorb carbon dioxide; decompressing to normal pressure for the desorption of adsorbed carbon dioxide for 60-100sec so as to recover carbon dioxide with a high purity.
