Study of CO2 Hydrate Growth Process Based on Diffusion-Controlled Reaction

Article Preview

Abstract:

A one-dimensional mathematical model of mass transfer during CO2 gas hydrate film formation at the boundary between the gas and water is established by analyzing the process of the static system. According to the model, we can get the concentration distribution of free CO2 in the hydrate film along with the time, and the conversion rate of hydrate with time can also be obtained. The results calculated at specific experiment condition in the system are analyzed. It indicates that the conversion rate can reach about 85% after 10 hours under static condition with 3.5MPa pressure and 0.5°C temperature by pure water when the initial reaction liquid depth is 20 mm
