dioxide (CO2) gas mixture for its potential application as gas hydrate
inhibitors for CO2 hydrate (Type I). Induction time was the parameter
obtained using High Pressure Kinetics Measurement (HPKM) for a bulk volume of
130 mL. The temperature for all the experiments was kept constant at 275.0 K
(2°C) with the pressure varied at 25, 30 and 35 bar. The ionic liquid was
tested as a kinetic inhibitor as well as thermodynamic inhibitor. In practice,
kinetic inhibitors are typically used at concentrations of 1 wt.% or less, thus,
the experiment was conducted for three different concentrations of the ionic
liquid; 0.1, 0.5 and 1.0 wt.% at varying pressures. EMIM BF4 at a concentration
of 10.0 wt.% was also tested but at 30 bar only to study the effectiveness of
ionic liquid as thermodynamic inhibitors. It was found that the induction time
for CO2 hydrate formation increases in the presence of more highly
concentrated ionic liquid. However, at high concentration of 10.0 wt.%, EMIM
BF4 does not show significant changes in the induction time as CO2
hydrate inhibitor.]]>Perry, R.H. and D.W. Green,20088th Edn.,Pages: 2851Pages: 2851Sabil, K.M.,20092009Moraveji, M.K.,20127505513Sloan, E.D. and C.A. Koh,20073rd Edn.,Pages: 752Pages: 752
