The Amount of Gas Consumed in the Process of Hydrate Formation for the Systems of Water + Carbon Dioxide and Water + TBAF + Carbon Dioxide

According to Kyoto protocol, carbon dioxide is one of the six large greenhouse gases which causes global warming. Therefor it is very important to prevent it from entering the atmosphere. The gas hydrate technology is one of the newest methods of carbon dioxide separation, but slow kinetics of this technology is one of the major obstacles to industrialize the process. The induction time of carbon dioxide hydrate formation and the amount of gas have been consumed for the systems of water carbon dioxide and water TBAF carbon dioxide were measured in this research. The experiments were done in a 169 cm3 batch reactor and at temperature 278.15 K and initial pressure 3.8 MPa. Utilization of 5 wt% TBAF decreases the induction time of hydrate formation from 73 min to 0.9 min. The amount of carbon dioxide consumed within 40 min and 350 min of experiments was measured and reported. Utilization of 1, 4, and 5 wt% TBAF within 40 min of experiments increase the amount of carbon dioxide consumed 18.5% ,39.3%, and 71.9%, respectively.
