Vapor pressures of aqueous blended-amine solutions containing (TEA/AMP/MDEA)Â +Â (DEA/MEA/PZ) at temperatures (303.15-343.15)Â K

► We measure vapor pressures of aqueous mixed-amine solutions from 30 to 70 °C. ► Mixed-amine solutions include {TEA or MDEA or AMP} + {MEA or DEA or PZ}. ► All the aqueous amine solutions exhibits lower vapor pressures than water at a constant temperature. ► Vapor pressure of solution decreases with increasing amine concentration at a constant temperature.
