文摘
Vapor-liquid equilibrium (VLE) for two binary aqueous solutions of novel CO2 capture solvents were studied experimentally in a modified Swietoslawski ebulliometer at 70, 80 and 100 ¡ãC for one compound (Compound A) and at 50, 60, 80 and 100 ¡ãC for another compound (Compound B). The total pressure (P) as function of temperature (T) was measured for these binary solutions and the composition of the vapor (y) and liquid (x) phases were analyzed. Experimental P-T data were fitted to an Antoine equation.
Experimental activity coefficients for Compound A were calculated using P, T, x, y data and activity coefficients for Compound B were calculated using only P, T, x data. Activity coefficients of Compound A and D were fitted to Wilson and NRTL models.
The total pressure (P) as a function of temperature (T) was measured for one novel ternary solvent system, containing Compound A, B and water at a certain concentration ratio.
