Mass balance principe

WebWe now put these two together and introduce mass balances. A mass balance is an incredibly useful tool in chemical engineering based on the principle of conservation of mass, which states that mass cannot magically be produced or destroyed – it has to come and go from somewhere. In a system, mass can either be carried in/out by means 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.

WebMass balance is quite flexible and can be applied at either a product or substance (e.g., ingredient) level. It can allow for changes over time and changes in stocks of material held at various points in the process. One important advantage of the mass-balance method is that there are established procedures for using it.16 In WebIt should be born in mind that the materials balance, as an identity for all kinds of processes using material inputs, cannot give any information about a specific technology at hand, but only...
