Abstract

The phase equilibrium of CO2 hydrates on various types of porous media is studied experimentally and modeled. The model lies in the consideration of different surface properties of the media. The experiments are conducted under controlled conditions to measure the hydrate formation conditions. The proposed model is based on the Chen-Guo theory and incorporate the surface property parameters for each type of porous media. The model’s predictions are validated by comparing them to experimental data, and it is found to fit well. Furthermore, the accuracy of model is compared with other existing models, and it is observed to have higher precision. The study contributes to a better understanding of CO2 hydrate formation on different porous media and provides a reliable model for predicting phase equilibrium conditions in such systems.
