System and method for targeted gas desorption from sorbents via an eductor pump mechanism

A method for selective desorption, the method comprising:

• placing a sorbent loaded with a target gas and at least one non-target vapor in a sealed chamber;
• circulating a fluid sorbent stream through an eductor pump into the sealed chamber such that the eductor pump creates a target pressure in the sealed chamber;
• adjusting a flow rate of the fluid sorbent stream to control an absolute pressure within the sealed chamber;
• adjusting at least one of a chemical formulation or a temperature of the fluid sorbent stream to establish a partial pressure within the sealed chamber that is lower for the target gas than for the at least one non-target vapor, thereby preferentially desorbing the target gas from the sorbent;
• separating the desorbed target gas from fluid sorbent stream by an entrained-gas separator located downstream of the eductor pump;
• and
• regenerating the fluid sorbent stream by removing the target gas therefrom by a regeneration unit located downstream of the entrained-gas separator and returning the regenerated fluid sorbent stream to a pump located downstream of the regeneration unit and upstream of the eductor pump.
