Abstract
The present invention relates to a fixed bed hypersorber having moving ports for injecting and withdrawing fluids which can be used for fractionation of gaseous mixtures in a fixed bed filled with absorbents/adsorbents, where separation is brought about by contacting gaseous mixture in a counter-current fashion. The moving ports may take the form of pistons or pairs of tubes arranged concentrically, where one of the tubes has a straight slot and the other tube has a helical slot. Rotation of the tubes with respect to each other produces the moving port.
