Abstract
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 CO2, and the absorptive liquid can be liquid water-free tetraethylenepentamine (TEPA). The apparatus is advantageously manufacture using additive manufacturing techniques.
Claims20
A species extraction apparatus comprising:
- an additively manufactured body supporting a matrix structure, wherein the matrix structure has a surface area to volume (S/V) ratio of greater than 180 m−1 and wherein the body supporting the matrix structure is additively manufactured using a predetermined energy density of from 0.5 J/mm to 5 J/mm;
- and
- an absorptive liquid for removing at least one species from a working fluid that contacts the matrix support structure.
A method for liquid-based extraction comprising:
- i) forming an apparatus via additive manufacturing, the apparatus comprising a body supporting a matrix structure comprising cellular units, and having a surface area to volume (S/V) ratio of greater than 180 m−1, wherein the body supporting the matrix structure is additively manufactured using a predetermined energy density of from 0.5 J/mm to 5 J/mm;
- ii) loading the apparatus with an absorptive liquid to form a loaded apparatus;
- and
- iii) contacting the loaded apparatus with a working fluid;
- wherein mass transfer of at least one substance in the working fluid occurs across the interface between the working fluid and the absorptive liquid.
