Introduction
Material balance is one of the most fundamental calculations in process engineering. It ensures that mass is conserved throughout a process system.
What Is a Material Balance?
A material balance is a calculation that accounts for the mass entering and leaving a system.
It is based on the law of conservation of mass, which states that mass cannot be created or destroyed.
Basic Equation
Input = Output + Accumulation
In steady-state processes, accumulation is usually zero.
Why Material Balance Is Important
Helps design equipment size
Used in process simulation
Essential for plant operation analysis
Example Applications
Reactor design
Distillation columns
Mixing tanks
Conclusion
Material balance calculations are essential tools for process engineers when designing and analyzing industrial plants.
