Phase equilibrium and characterization of ionic clathrate hydrates formed with tetra-n-butylammonium bromide and nitrogen gas

Phase equilibrium and characterization of ionic clathrate hydrates formed with tetra-n-butylammonium bromide and nitrogen gas

We report the three-phase (gas–hydrate–aqueous) equilibrium measurements and phase characterization of ionic clathrate hydrates formed in a nitrogen + tetra-n-butylammonium bromide (TBAB) + water system. The measurement conditions used were 0.0029 ≤ xTBAB ≤ 0.0257 (0.05 ≤ wTBAB ≤ 0.32), 280 K ...
