In physics, a mass balance, also called a material balance, is an application of conservation of mass to the analysis of physical systems. By accounting for material entering and leaving a system, mass flows can be identified which might have been unknown, or difficult to measure without this … See more The general form quoted for a mass balance is The mass that enters a system must, by conservation of mass, either leave the system or accumulate within the system. Mathematically the … See more A simple example can illustrate the concept. Consider the situation in which a slurry is flowing into a settling tank to remove the solids … See more A mass balance can also be taken differentially. The concept is the same as for a large mass balance, but it is performed in the context of a limiting system (for example, one can consider the limiting case in time or, more commonly, volume). A … See more In industrial process plants, using the fact that the mass entering and leaving any portion of a process plant must balance, data validation and reconciliation algorithms may be … See more Mass balances can be performed across systems which have cyclic flows. In these systems output streams are fed back into the input of a unit, often for further reprocessing. Such systems are common in grinding circuits, where … See more In reality, reactors are often non-ideal, in which combinations of the reactor models above are used to describe the system. Not only chemical reaction rates, but also mass transfer rates … See more • Bioreactor • Chemical engineering • Continuity equation • Dilution (equation) • Energy accounting See more WebThis calculation-based principle offers multiple advantages: It reduces greenhouse gas emissions and fossil feedstock inputs, while the quality and properties of a product remain the same. As a result, the products can be processed exactly like conventionally produced materials. There is therefore no need to adapt formulations, plants or processes.
