Popis:	A high pressure, temperature-controlled sapphire equilibrium cell is used to observe the nucleation and growth behavior of gas hydrates in bulk water or on spheres suspended in water. Gas hydrate crystals are grown on positively and negatively charged latex spheres. The experiments have been conducted on an ethane-water system that is known to form structure I hydrate. Experiments were carried out at temperatures between 278.0 K and 278.6 K and pressures ranging from 1,300 kPa to 1,500 kPa. A light scattering apparatus was used to monitor the hydrate formation process. In particular, the photomultiplier voltage was recorded over time in order to observe the effects of latex spheres on the nucleation and growth of gas hydrates. More experiments need to be performed to better ascertain the hydrate nucleation and growth behavior in the presence of latex spheres.
