The article presents the mathematical model of non-ideal binary solution evaporation from the emergency spill surface, which allows determining the process characteristics with the heat and mass transfer in the liquid phase. This study compares the results of numerical experiments obtained by: a) subject to thermo-gravitational convection in the layers of the evaporating liquid, b) using the assumption of ideal mixing in the whole volume of the solution.
