The operation conditions are varied to determine the system liquid phase stability range at the standard and critical conditions. A case study involving 30 wt K 2CO 3, H 2O standard system at pressure of 1 bar and temperature range from 280.15 to 366.15 K has been studied. The estimated solubility index, viscosity, water activity, and density which obtained from the simulation showed a good agreement with the experimental work. Furthermore, the saturation temperature of the solution has been estimated. %Z cited By 0
