The balance simulation problem (BSP) is one of the most frequent problems occurring in the design and intensification of integrated chemical technologies. In contrast to the simulation problem, BSP does not always have a solution. It is therefore important to know such values of the independent variables (some parameters of apparatuses and some balance quantities) for which the solution does not exist. To estimate the intervals of the independent variables for which no solution of the BSP exists, the results of a simulation under uncertainty are used.
