HydraCHEK is a fast and user-friendly analytical solution that measures the concentration of hydrate inhibitor and salt in produced water samples taken from a pipeline. It provides a convenient way to monitor the hydrate inhibition of a production system and avoid the significant costs of hydrate inhibitor over use.
HydraCHEK has been extensively tested in the field and has been proven to develop robust calibrations for detecting different hydrate inhibitors and salt. Ultimately, HydraCHEK is an economically ideal solution to the excessive hydrate inhibition issue and that is why it is in everyday use by major operators around the globe.
HydraCHEK measures two independent physical parameters; the speed of sound and the electrical conductivity to determine two unknown parameters; hydrate inhibitor and salt concentration.
The measured speed of sound and electrical conductivity of a sample are input into an artificial neural network correlation that allows both the salt and inhibitor concentration to be determined.
If a calibration already exists for the hydrate inhibitor and salt to be measured then the system can be deployed immediately and no adjustments are necessary. For example we have already developed HydraCHEK calibrations for the main thermodynamic hydrate inhibitors (Methanol, MEG, Ethanol), which can be used to detect the inhibitor and salt concentration for any production system, provided the concentrations are within the measurement range of the device and calibration.
HydraCHEK only requires calibrating for a system if we have not developed a calibration for the hydrate inhibitor to be detected i.e. a new KHI formulation.
