Methyl-tert-butyl ether (MTBE) and Methanol (MeOH) have been known as effective fuel oxygenates to increase the octane number, improve fuel performance, and cut the environmental pollutants. However, their high solubility in water limits their usage in the petroleum industry field regarding the loss of fuel homogeneity. In this work, the liquid-liquid phase equilibrium of the ternary system of MTBE – Methanol –Water. Experiments have been studied at different mole fractions, various temperatures; 0°C, 25°C, and 50°C, and at several pressures; 1.0 atm, 1.5 atm, and 2.0 atm. This work represents a combination of practical laboratory experimental results and simulation sets utilizing Aspen HYSYS software version 7.2. The results show that Aspen HYSYS simulation data are proficient with the output data developed from the laboratory experimental laboratory measurements and thus it is capable to correlate software simulation with practical data for the studied systems with realistic accuracy. This protocol aims to optimize the oxygenate composition, pressure, and temperature during the usage of MTBE – MeOH as a common fuel oxygenate additive.
