Abstract

A method of determining a liquid volume fraction in a multi-phase gas is disclosed. The method includes: a) measuring a first compressor operating parameter; b) selecting a tentative liquid volume fraction of the gas processed by the compressor; c) based on stored data representing a compressor operative curve for the tentative liquid volume fraction, determining an estimated value of a second compressor operating parameter, as a function of the first compressor operating parameter; d) measuring an actual value of the second compressor operating parameter; e) comparing the actual value of the second compressor operating parameter to the estimated value of the second compressor operating parameter and determining an error therefrom; f) based on the error, selecting a different tentative liquid volume fraction and repeating (c) to (e) until an error value equal to or lower than an error threshold is obtained.
