In one aspect, a method for selectively removing at least one target component from a multicomponent feed fluid using a removal system, the system including a feed chamber having an inlet and an outlet, a permeate chamber, and a membrane for separating the feed and permeate chambers. The membrane is selective for the at least one target component. The method includes: in a first period, introducing the feed fluid into the feed chamber through the inlet, thereby exposing the feed fluid to the membrane, while allowing flow out of the outlet, wherein at least a portion of the at least one target component in the feed chamber is removed, either by absorption or adsorption, by the membrane; in a second period, simultaneously halting flow through the inlet and the outlet of the feed chamber, thereby trapping the feed fluid within the feed chamber; and providing a component-gradient across the membrane in both the first and second periods, thereby continually removing the at least one target component and regenerating the membrane.
