Phase Equilibria of CO2 Hydrate in the Aqueous Solutions of N-Butyl-N-methylpyrrolidinium Bromide
This work aims at reporting the dissociation pressures of carbon dioxide simple hydrates in the aqueous solution of N-butyl-N-methylpyrrolidinium bromide at four different mass fractions (0.01, 0.05, 0.10, and 0.20) in the pressure range of (2.34 to 3.13) MPa and in the temperature range of (276.63...
