US Patent Issued to Schlumberger Technology on Nov. 25 for "Carbon dioxide multiphase flow measurement based on dielectric permittivity" (Singaporean Inventor)

ALEXANDRIA, Va., Nov. 25 -- United States Patent no. 12,480,792, issued on Nov. 25, was assigned to Schlumberger Technology Corp. (Sugar Land, Texas).

"Carbon dioxide multiphase flow measurement based on dielectric permittivity" was invented by Cheng-Gang Xie (Singapore).

According to the abstract* released by the U.S. Patent & Trademark Office: "Methods and apparatus for determining mass flow rate of a CO2 rich stream using dielectric permittivity are described. A method herein measures a dielectric permittivity of a CO2 rich stream; determines a density of the CO2 rich stream from the measured dielectric permittivity; determines a viscosity of the CO2 rich stream from the measured dielectric permittivity; measures a pressure drop of the...
