Equally fundamental is the law of conservation of energy. Energy analysis can show the energy efficiency of a process but it does not tell. The main processes were simulated using mass and energy balance equations, and the results were validated by means of experimental data. Mass balance of the system the mass balance of the system show the relation between the mass input to the mass output and the mass of remaining or generated in the system for the given mass change at time say 2 t 1 dt dt d m. Heat and material balances hsc chemistry, software for process. In order to analyze the performance and feasibility of the proposed system, it is necessary to perform an energy simulation of mass and energy balance between. Performing reactive mass and energy balances rb performing reactive mass and energy balances when reactions occur, material balances become more difficult, and energy balances are often more important.
