Cooling systems for Chemical plants with mass balance & energy balance
According to the most fundamental and basic laws of physics, Energy can
neither be created nor destroyed, and so is the physical states or mass.
However, they can be converted form one form to another to maintain the
balance or which is what called as conservation of energy/mass. These two
laws has been utilized in several other derivations of physics and other field
formulas and statements.
So, in order to have a little grasp of energy and mass balance, we will get to
know about each of them in brief in this Article.
Mass balance
According to the conversation of mass principle, mass in any physical state
can neither be created nor destroyed. If there is any increase in mass of a
physical state, then, there is an equivalent decrease in the mass of any other
physical state at the same so as to balance that mass.
If we try to write the mass balance in a formula, it can be written as:
Mass at time+ change in mass= mass at time t + new mass added in one
physical state – mass decreased in any other physical state + some mass
generate due to chemical reactions
Where, the difference in the time, or time utilized during the mass change
should be constant in every state transformation.
Energy balance
Efficient utilization of energy is of utmost importance, and that’s what law of
conservation of energy implies, accordingly, any change in energy in one form
in a particular period of time is equivalent to the same amount of energy
change in that particular period in any other form of energy. Or, we can say
energy can neither be created nor destroyed, and that’s why efficient
utilization of energy is important.
For example, in case of burning of coal, chemical energy present inside the
coal is converted into heat energy, and such processes occur at every
moment somewhere where one form of energy is converted onto another
form.
In physics and chemistry, energy balance is referred to as first law of
thermodynamics, and it implies that like mass, energy is also a conservative
form of things and cannot be created but can be converted from one form to
another.
Just as for better understanding, few forms of energy are:
However, energy balance has several other definition based on the industry
they are utilized, like in chemistry, the definition says that energy cannot be
related or destroyed. While in geography, incoming solar radiation and
outgoing wave radiation, the difference between these two is often referred as
energy balance.
Similarly, there is a different definition in biology, but again, the core concept
for the definition has been derived all from here that energy cannot be created
or destroyed.
Mass and energy balance is certainly the most fundamental and basic laws in
physics or chemistry but they do hold utmost importance in environment and
also while deriving many other significant formulas in chemistry.

- Potential energy
- Heat energy
- Internal energy
- Electromagnetic energy
