The effect of residual structure on hydrate formation
- Colorado School of Mines, Golden, CO (United States)
The combined statistical mechanics and classical thermodynamics approach of Parrish and Prausnitz (1972) was instrumental in providing the natural gas industry with a practical tool to predict hydrate formation. This extension of the van der Waals and Platteeuw model is perhaps the most prevalent use of statistical thermodynamics by the natural gas industry. In addition the Parrish and Prausnitz approach spawned many years of academic research in the laboratories of Kobayashi, Holder, and others. In the present work we present a continuation of Professor Prausnitz`s philosophy in bridging microscopic behavior with macroscopic observations. A microscopic model for hydrate kinetic formation is presented, together with experimental observations of residual structure which can explain phenomena from the laboratories of Bishnoi, Kobayashi, Makogon, and others. We also show how these microscopic phenomena can be used to generate a new (kinetic) type of hydrate inhibition.
