Abstract

In this study, the kinetic effects of two IONIC LIQUIDS (ILs), namely 1-butyl-3-metylimidazolium tetrafluoroborate ([Bmim][BF4]) and 1-butyl-3-metylimidazolium methyl sulfate ([Bmim][MS]), on the formation of carbon dioxide hydrate were investigated. The kinetic study confirmed that two ILs at concentration of 0.6 wt% and an initial pressure of 35 bar decreased the induction and nucleation time of carbon dioxide hydrate. Therefore, they can be considered as KINETIC PROMOTERs. The PROMOTION FACTOR of [Bmim][BF4] and [Bmim][MS] were 68% and 52% respectively. Subsequent to the kinetic study of CO2 hydrate formation, the KINETIC MODELING of CO2 hydrate formation was carried out using the steady-state approach via a modified multi-step chemical reaction mechanism. The proposed model could reliably predict the pressure-time profiles; the experimental and the data calculated based on the integrated kinetic equations are in good agreement. The results showed that the proposed model could be used for the accurate prediction of the nucleation and crystal growth of CO2 GAS HYDRATEs.
