Influence of Gas Supply Mode on CO₂ Hydrate Formation in Water Spraying Reactor

Abstract:

In order to study the influence of gas supply modes on CO₂ hydrate formation characteristics, a specific water spray gas hydrate formation apparatus was designed. The gas consumption and temperature variation in the process of CO₂ hydrate formation under continuous and oscillating gas supply modes were researched. The experimental results showed that hydrate formation rate in the oscillating gas supply mode was greater than in the continuous gas supply mode, which indicates mass transfer driving force caused by disturbance in oscillating gas supply mode is larger than that of continuous gas supply mode. Additionally, under the same initial pressures and the same gas supplying mode, the lower the initial temperature, the larger the heat transfer drive force, and the faster the hydrate formation rate.
