Claim:
A high volumetric-efficiency thermally integrated system for capturing a target gas from a process gas stream, comprising: a monolithic body and a distribution system, wherein: the monolithic body comprises: a first monolith comprising a first plurality of discrete channels through the first monolith and parallel to a first flow axis of the monolithic body; and a second monolith adjacent to the first monolith and comprising a second plurality of discrete channels through the second monolith and parallel to a second flow axis of the monolithic body; the first plurality of discrete channels and the second plurality of discrete channels are arranged such that individual channels of the first plurality of discrete channels are in thermal communication with individual channels of the second plurality of discrete channels; the first plurality of discrete channels are not in fluidic communication with any of the second plurality of discrete channels; first partition walls of the first plurality of discrete channels and second partition walls of the second plurality of discrete channels comprise sorbent surfaces of a sorbent material that reversibly adsorbs the target gas from the process gas stream; the high volumetric-efficiency thermally integrated system is reversibly switchable between: a first state in which the distribution system simultaneously supplies the process gas stream to the second plurality of discrete channels and a purge stream to the first plurality of discrete channels, the target gas being adsorbed from the process gas stream in the second plurality of discrete channels while being desorbed into the purge stream in the first plurality of discrete channels; and a second state in which the distribution system simultaneously supplies the process gas stream to the first plurality of discrete channels and the purge stream to the second plurality of discrete channels, the target gas being adsorbed from the process gas stream in the first plurality of discrete channels while being desorbed into the purge stream in the second plurality of discrete channels.
