Mass Transport Properties on Time Series Variation of CO2 Hydrate Film Thickness

Abstract The purpose of the present study is to develop the model predicting CO 2 hydrate film thickness for CCS. First, we measured variation of CO 2 hydrate area at the interface between water and liquid CO 2 interface when hydrate generation along the interface. Consequence CO 2 hydrate cover the interface completely, CO 2 hydrate film thickness was measured by interferometry method under various temperature condition. Second, the model which predicts CO 2 hydrate film thickness based on mass transfer phenomena was developed, and compared calculated film thickness to measured film thickness. Finally, using is model to predict hydrate film thickness and storage term under actual sea condition (e.g. temperature, pressure, ambient flow velocity), and amount of CO 2 from 1 GW class thermal power plant.
