Introduction

Mass Balance

By the use of mass balances scientists can: Calculate the amounts of raw materials needed for a process, estimate the quantity of product that can be made, test for errors such as leaks or catalysts that do not work properly and allows us to be aware of the full process. Mass balances can also tell us what’s in an unknown stream coming from a process. (CAE Mass Balances CMc Week 1, CAE Lecture notes, University of the west of Scotland, 2013/2014)

In science the capacity for work is called Energy. Energy can be found in a number of forms which can be altered from one form to another but these changes are restricted by a fundamental law of Physics, The Conservation of Energy Principle. This can be stated as:

“Energy can neither be created nor destroyed”

Or

“The total energy of an isolated system remains constant” (http://hyperphysics.phy-astr.gsu.edu/hbase/conser.html#coneng, 18/03/2014, 18:35)
