WebA mass balance is the starting point of every study in Chemical Engineering. This page is explaining how to perform a mass balance in a chemical reactor. The general … 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 differential mass balance is used to generate differential equations that can provide an effective tool for modelling and understanding the target system. Weba) The mass balance relationship is an important concept in chemical engineering that represents the conservation of mass in a process.
