with the fact that CO2 hydrate is thermodynamically more stable
than N2 and O2 hydrates. However, the measured incipient hydrate
formation pressure for flue gas is prohibitively high and needs to
be significantly decreased for hydrate-based technology applications.
In what follows, two additives TBAB and TBPO were respectively
tested for their effects on hydrate phase equilibrium
conditions, and the results are tabulated in table 4 and plotted in
figures 3 and 4, respectively.
