Review of water salinity measurement methods and considering salinity in measuring water area phase fraction of wet gas

Abstract

Accurate measurement of water area phase fraction is one of key factors for precise measuring of wet gas flow rate. As variation in water salinity affects water area phase fraction measurement, therefore for having accurate water area phase fraction measurement, it is required to measure water salinity and take that into account in water area phase fraction measurement. In this paper, various methods for measuring water salinity in wet gas fluid are reviewed. Then the methodology for considering measured water salinity in water area phase fraction measurement is explained. Since accurate measurement of water area phase fraction is necessary for having precise wet gas flow rate measurement, therefore by considering water salinity in water area phase fraction measurement, the overall accuracy of wet gas measurement increases. In addition, knowing water salinity is very valuable in wet gas flow measurement as water breakthrough can be sensed using the measured salinity.
