Abstract

The effect of salinity towards methane hydrate formation and induction time was modelled using CMG STARS. Salinity greatly influenced gas hydrate formation and dissociation due to its ability to act as an inhibitor by delaying the nucleation of methane hydrate. However, most of the developed kinetics model did not take into consideration of salts in porous media during the simulation. In this research, the objectives are to simulate and investigate the induction time of methane hydrate formation using Clarke and Bishnoi kinetic model in the presence of saline water. The simulation is conducted using different salinity concentration of 0 ppm, 5000 ppm, 15000 ppm, 25000 ppm,35000 ppm, and 40000 ppm. The presence of salts in porous media increases the induction time from 464 minutes to 515 minutes.
