  • CO2 concentration measurement in dry gas mixtures
    Patent number: 10942144
    Abstract: Described herein is an apparatus and methods for characterizing a fluid composition including exposing electrolyte to one fluid mixture, collecting a signal from an electrode in contact with the electrolyte, and simultaneously exposing the electrolyte to a second fluid, collecting a signal from a second electrode in contact with the electrolyte exposed to the second fluid, and comparing the signal difference between the electrodes with the Nerst equation wherein the temperature of the electrolyte is above 488° C. Carbon dioxide, nitrogen, and/or oxygen may be present in the fluid and/or the second fluid.
    Type: Grant
    Filed: October 3, 2017
    Date of Patent: March 9, 2021
    Assignee: Cameron International Corporation
    Inventors: Albert Perez, Terizhandur S. Ramakrishnan, Wenlin Zhang, Li Jiang, Roy Koveleski, Quincy K. Elias
