Abstract

The kinetics of methane gas hydrate formation was obtained by different dual and dual mixed impeller experiments with surface baffle at 42.5 bars pressure and 2 degrees C temperature. The outcomes indicated that induction time is lower in radial flow experiments compared to mixed flow experiments due to better gas liquid contact, uniform shear stress and good pumping capacity compared to mixed flow ones with values less 15 min. Radial flow experiments showed higher values in hydrate yield although the duration of hydrate formation in radial flow experiments is less compared to mixed flow ones confirming the above outcomes with values more than 5%. Radial flow impellers indicated higher values in rate of hydrate formation compared to mixed flow impellers.
