Abstract
Methods and apparatus for determining mass flow rate of a COrich stream using dielectric permittivity are described. A method herein measures a dielectric permittivity of a COrich stream; determines a density of the COrich stream from the measured dielectric permittivity; determines a viscosity of the COrich stream from the measured dielectric permittivity; measures a pressure drop of the COrich stream flowing through a flow restriction; and determines mass flow rate of the COrich stream using the measured pressure drop, the determined density, and the determined viscosity.
