Abstract

Gas hydrates are ice-like solids in which gas molecules are enclathrated within cages composed of hydrogen-bonds. Measuring hydrate formation is not only useful for probing multi-component nucleation processes but also has direct relevance to oil and gas production systems where hydrates can block subsea flowlines. In this thesis, a novel apparatus, the high-pressure-stirred, automated-lag-time-apparatus (HPS-ALTA) is developed and used to obtain large numbers of independent hydrate formation events. These enable the construction of high-resolution hydrate formation probability curves which can be used to validate and test theoretical models, as well as enabling their application in industrial hydrate management decisions.
