Abstract
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 CO2 rich stream flowing through a flow restriction; and determines mass flow rate of the CO2 rich stream using the measured pressure drop, the determined density, and the determined viscosity.
