Mass balance - Wikipedia

Mass balance - Wikipedia

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 technique The exact conservation law used in the analysis of the system depends on the context of the problem .

Dynamic Simulation and Control of the Bayer Process A ,

In the Bayer process, used for the production of alumina from the bauxite ores, there are frequent disturbances and a large number of interacting processes which incorporate considerable dead time The challenge to any alumina refinery is to maximize the production of alumina (plant flow and yield) and minimize the energy costs per ton of alumina subject to constraints on liquor sodium oxalate .
