  • Patent number: 11439927
    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.
    Type: Grant
    Filed: October 22, 2019
    Date of Patent: September 13, 2022
    Assignee: EXXONMOBIL TECHNOLOGY AND ENGINEERING COMPANY
