Abstract
For the design of spray propellants, bubble point pressures were measured for binary mixtures of ethanol with propane, dimethyl ether (DME) or trans-1,3,3,3-tetrafluoropropene (R1234ze(E)), with a static type apparatus at (293.15–313.15) K. Experimental data were correlated with the Peng-Robinson (PR) and Stryjek-Vera (PRSV) equations of state using the Wong-Sandler (WS) mixing rules. The NRTL activity coefficient model in the WS mixing rules was effective for correlation of systems that exhibited large non-idealities (ethanol - propane, ethanol - R1234ze(E)). Correlation of the bubble point pressures with the PRSV equation of state and WS mixing rules was to within an average of 2.391% absolute deviation in pressure for all systems, which is considered to be sufficient for design of spray devices with propellants that have low global warming potential.
