Résumé
Hydrate formation experiments were conducted for two single gas and three gas mixtures. These systems are relevant to technologies under development for natural gas hydrate storage and transportation and for CO2 capture and sequestration. CH4/water, CH4 (90.5%)/C3H8 (9.5%)/water and CH4 (91%)/C2H6 (9%)/water are the hydrocarbon systems. CO2/water and CO2 (38.1%)/H2 (59.4%)/C3H8 (2.5%)/water are the systems studied for CO2 capture and sequestration. Two types of experiments were conducted for the above systems. One was conducted by dispersing water in silica sand, while the other in a stirred tank vessel. Both types of experiments were conducted at a constant temperature and in a closed system having the same experimental pressure at the start of the experiment. The presence of silica sand was found to enhance the kinetics of hydrate formation significantly and there by resulting in a higher percent of water conversion to hydrates in lesser time for all the systems studied.
