Abstract
A high-pressure, temperature controlled sapphire cell has been designed and constructed to study the nucleation behaviour of clathrate hydrates under pristine experimental conditions. Light scattering optics and detection equipment have been installed to monitor the incipient hydrate phase development and characterize the early stages of crystal growth. The aspects of light scattering theory that are relevant to the nucleation of clathrate hydrates are outlined and applications of the theory to particle size characterization are described. Preliminary experiments have demonstrated that within the detection limit of the apparatus, the hydrate phase was not present in sufficient size or number prior to a nearly instantaneous appearance of the phase. A series of investigations to identify nucleation process variables have identified a temperature history of the aqueous phase and the efficacy of mechanical or thermal perturbations on inducing hydrate formation. An argument that nucleation is a stochastic process is developed.
