 A systematic kinetic study to evaluate the effect of tetrahydrofuran on the clathrate process for pre-combustion capture of carbon dioxidePonnivalavan Babu, Hong Wen Nelson Ong and Praveen Linga Energy, 2016, vol. 94, issue C, 431-442 Abstract: THF (Tetrahydrofuran) is the most commonly employed promoter for the gas hydrate formation pertaining to applications like carbon dioxide capture and energy storage (for natural gas and hydrogen). In this work, THF was investigated as a promoter for pre-combustion capture of carbon dioxide (CO2) from fuel gas mixture (CO2/H2) in a systematic manner. 0.5, 1.0, 3.0 and 5.56 mol% THF solution were employed with different driving force conditions to study the effect of pressure, temperature and composition of gases in hydrate. The kinetic performance of the CO2/H2/THF gas hydrate system was evaluated by reviewing the IT (induction time), normalized gas uptake, normalized rate of hydrate formation and the hydrate phase composition. The optimum operating conditions and optimum THF concentration in this study was found to be 6.0 MPa, 282.2 K, and 5.56 mol% THF respectively. 5.56 mol% THF solution yielded an average gas uptake of 13.9 mmol of gas/mol of water for hydrate growth and an average normalized rate of hydrate formation of 1679.8 mmol s−1 m−3.
