Based on water spraying technology

the characteristics of CO2 hydrate formation in spray reactor were investigated experimentally. The effects of temperature and pressure in the reactor

the coolant temperature in entrainment and the use of buffer tank on CO2 hydrate formation characteristics were studied. Compared with CO2 hydrate formation under static conditions

the pressure drop in the spraying process was larger

and CO2 hydrate was formed much faster. The water was sprayed into gas

providing much more gas-water contact surface. The experimental results showed that the duration of CO2 hydrate formation was about 20 minutes in the presence of a buffer tank. However

under the same working condition

the duration of CO2 hydrate formation was about 40 minutes without a buffer tank. The buffer tank sent CO2 into the spraying system evenly and stably

which enhanced the spraying effect and doubled the CO2 hydrate formation rate. The experimental results provide an important reference for the analysis of CO2 hydrate formation and engineering applications.
