A species extraction apparatus for liquid-based extractions is disclosed herein. The apparatus comprises a body supporting a matrix structure comprising cellular units. The apparatus is configured to uptake an absorptive liquid, and the absorptive liquid can remove at least one species from a working fluid that contacts the apparatus. In certain embodiments, the at least one species can be CO, and the absorptive liquid can be liquid water-free tetraethylenepentamine (TEPA). The apparatus is advantageously manufacture using additive manufacturing techniques.

Species extraction

A nozzle and methods of gas stripping utilizing the nozzle are provided. A nozzle is provided comprising a ceramic nozzle assembly comprising an inlet at one end of a cylindrical portion, an outlet at one end of a conical portion; the cylindrical portion transitioning to the conical portion at an end of the cylindrical portion distal from the inlet; the conical portion transitioning to the cylindrical portion at an end of the conical portion distal from the outlet; and a ceramic vane assembly within the cylindrical portion; the vane assembly comprising a central vane support located substantially concentrically within the cylindrical portion, and a plurality of angled vanes extending from the central vane support to an inner wall of the cylindrical portion; wherein the ceramic nozzle assembly and the ceramic vane assembly are manufactured such that the two assemblies comprise a single piece of ceramic.
