CO2 Hydrate Formation in Falling Film of Water

A preliminary investigation is done in order to evaluate the possibility of incorporating falling film reactors for gas hydrate formation. A rocking cell containing a thin layer of water is used to create falling film condition. Two sets of experiments are carried out to compare induction time and hydrate growth rate in falling film condition and stationary film condition. Experimental results show that using falling film of water in the reactor reduces induction time and the minimum supersaturation required in the system for massive hydrate growth to occur. It is also observed that the apparent rate constant for hydrate growth is an order of magnitude higher in falling film condition compared to stationary film condition
