Material and energy balances are quantitative accounts of the redistribution of material and energy that occurs when something happens. They are a basic tool of process engineering that can be used to solve many practical problems. Material and energy balances are based on the principles of conservation of mass and conservation of energy, respectively. The material balance equation is Input = Output + Accumulation, and the energy balance equation is Input = Output + Storage + Losses. Material and energy balances can be worked out quantitatively by knowing the amounts of materials entering...

Material and energy balances are based on the principles of conservation of mass and conservation of energy, respectively. The material balance equation is Input = Output + Accumulation, and the energy balance equation is Input = Output + Storage + Losses. Material and energy balances can be worked out quantitatively by knowing the amounts of materials entering into a process, and the nature of the process. The basic form of material and energy balances is Content of inputs = content of products + wastes/losses + changes in stored materials. The nature of the process decides the new material generation or loss. A chemical process in a system is always associated with some new component formation.
