Full TextAbstract
In this article, kinetics of carbon dioxide (CO2) hydrate formation was considered. The process of CO2 hydrate formation at different stirrer rates of 100-800 rpm and different temperatures ranging from 274 to 277 K was studied experimentally. The combination of two models based on mass transfer was used to model hydrate formation of CO2. Volumetric gas-liquid mass transfer coefficient (aL-V kL) and crystal growth constant was obtained by fitting on experimental data. In addition, an appropriate empirical correlation was applied for calculating the aL-V kL parameter and the fitted and calculated data were compared together. Furthermore, the effect of various operational parameters such as temperature, partial pressure, stirrer rate, gas-liquid volume ratio was investigated on kinetic rate constant of CO2 hydrate formation.
