<p>Apparatus and method for detecting the formation and dissociation of gas or clathrate hydrates in a fluid. The apparatus used comprises a piezoelectric crystal sensor and a signal analyser. The crystal sensor has a deposition surface in contact with the fluid. Under a range of pressures and or temperatures the resonant frequency or an electrical parameter dependent on the resonant frequency of the piezoelectric sensor is measured. There is a step change in the resonant frequency which occurs upon the formation or dissociation of a clathrate hydrate on the deposition surface, so that the formation or dissociation of said clathrate hydrate may be detected.</p> |
