Abstract: Embodiments include a method of magnetic swing absorption, which may include contacting a fluid mixture including one or more gases and a liquid absorbent in a separation chamber; absorbing at least one of said gases using the liquid absorbent, optionally in the presence of a constant inhomogeneous magnetic field; and desorbing the at least one absorbed gas from the liquid absorbent, optionally in the presence of the constant inhomogeneous magnetic field. Embodiments further include other related methods, related systems and apparatuses, and the like.

Abstract: Embodiments include methods (and related systems, devices, and apparatuses) for determining a sorption separation factor for a binary gas mixture by applying a magnetic field to at least a portion of a sorbent (604) disposed in a chamber of a magnetic susceptibility device; directing a first gas stream including a first gas compound into the chamber at a first pressure and temperature to obtain a first magnetic susceptibility measurement; directing a second gas stream including a second gas compound into the chamber at a second pressure and temperature to obtain a second magnetic susceptibility measurement; directing a binary gas mixture including the first gas compound and the second gas compound into the chamber at a third pressure and temperature to obtain a third magnetic susceptibility measurement; and determining a sorption separation factor based on the first, the second, and the third magnetic susceptibility measurements.
