ABSTRACT: Over the years, there has been a growing demand for renewable, natural sources of energy; owing to the global fuel crisis, majorly in fields of oil and coal. Gas hydrates have grabbed the attention, specially methane hydrate, as it has twice the amount of carbon quantity in all fossil fuels combined and evenly distributed around the world. Much study and field work have been done already to commercialize energy production from gas hydrates on a large scale. Methane hydrates are found in marine sediments. They usually have a guest gas molecule (methane) trapped between the molecules of water, depending on the hydration number. The driving force for gas to diffuse into the water phase and form hydrates in the solution is the decrease …show more content…
An undersaturation i.e. chemical potential of new phase is higher than the old, results in dissolution of the hydrate. The temperature and pressure parameters for methane hydrates cannot be replicated at lab scale and hence, a proxy molecule need to be used like tetrahydrofuran (THF), cyclopentane. Hydrate formation in capillaries helps us understand the complex-dynamic interactions between nucleation, gas diffusion and gas solubility. The observation of hydrate growth in a droplet shows that the hydrate shell does not grow homogeneously but advances in irregular manner that invade the water phase. We are analysing the THF and cyclopentane hydrate formation in glass capillaries at pore scale and and further investigating the transport at pore scale. The report starts with the required background and preliminary concepts to understand the formation and dissociation of gas hydrates. It contains experimental results for THF hydrates at atmospheric pressure and low temperature and hydrates of different composition of THF and water solution will demonstrate different characteristics. Future work for the project has also been discussed in the
