Laboratory study of CO2 hydrate formation induction time in the presence of Cocamidopropyl betaine (CAPB) and tetra-N-butyl ammonium bromide (TBAB) aqueous solutions
One way to separate, store, and recover greenhouse gases such as carbon dioxide by using clathrate hydrate formation. The present study employed induction time to assess the impact of amphoteric surfactants, namely Cocamidopropyl betaine (CAPB) and tetra-N-butyl ammonium bromide (TBAB), on the surface tension between carbon dioxide hydrate and water at varying temperatures, pressures, and concentrations. All experiments were performed in the pressure range of 25 to 35 bar under a temperature range of 275.15 K to 279.15 K. To manage the experiments, Design Expert version 13 software was employed to design the experiments via the Response Surface test method and Central Composite method through the Quadratic model. Laboratory results revealed that the induction time of carbon dioxide hydrate formation depends severely on surface tension, by adding CAPB to the system, the amount of surface tension and induction time decreased by 9% and 23%, respectively. Also, by adding CAPB and TBAB surfactants to the system, the surface tension and induction time decreased by 13% and 34%, respectively.
