Title:
HYDRATE MONITORING SYSTEM WITH MEASUREMENT OF SOUND VELOCITY AND ELECTRICAL CONDUCTIVITY
Document Type and Number:
WIPO Patent Application WO/2010/004289
Kind Code:
A3
Abstract:
A method for analysing a fluid containing one or more analytes of interest includes; measuring a plurality of properties of a sample fluid with unknown concentrations of the one or more analytes of interest; and using the measurements and a model of the relationship between the plurality of properties and concentrations of the one or more analytes to calculate the concentration of at least one of the analytes of interest. The model may be an artificial neural network. The method may be used to monitor the concentration of inhibitors of gas hydrate formation in a fluid. Apparatus for use in the method is also provided.
