Chemical process calculations are the mathematical models that represent the designs of chemical plants. These models help engineers analyze their design choices and evaluate alternative designs before investing money in building a plant. Chemical process calculations sit at the interface between thermodynamics, fluid mechanics, reaction engineering (kinetics), and unit operations (particularly mass transfer).

What is involved in chemical process calculation?
The main work required for establishing a mathematical model for a given plant is to derive an expression for every balance law in the device, called a ‘reaction mechanism.’ A suitable combination of conservation equations with appropriate boundaries conditions will then be used to solve the problem. For example, if one wants to determine product rates, one will need to distinguish between steady-state, dynamic (transient), and pseudo-steady state situations. The appropriate model for each case must be selected depending on the problem under consideration.
What are the types of chemical process calculations?
There are two different kinds of chemical process calculations: quantitative and qualitative. Quantitative calculations give an exact solution to a given problem, while qualitative ones only provide useful information without giving the exact solution in closed form.
The most common calculation types used in chemical engineering are mass balances, energy balances, and momentum balance equations sitting on top of the material and species balances. These models can further be subdivided into various categories depending on what they represent physically/mathematically, such as homogeneous, heterogeneous, kinetic, adiabatic, or isothermal models.
What are the uses of chemical process calculations?
The main use for these calculations is to design plant and machine components. These models also help in troubleshooting a plant before it becomes operational and post-processing data after the plant has started production. These numerical methods can optimize plants (either by changing operating conditions or changing equipment sizes) by minimizing costs subject to various constraints such as product quality requirements, heat integration with other plants, etc. They can also be used to reconstruct how changes in process variables affect the outcome of the system’s operation by recording historical data on their performance (for example, using what-if scenarios). The choice of which type of mathematical model to use depends on the kind of problem being studied (kinetic, dynamic, etc.). A chemical engineer will make this choice with input from process engineers and chemists.
The chemical process calculations are the most important aspect of your laboratory work. They provide numerical data for experiments, and they help you predict what will happen in future experiments, which is crucial when developing new medicines or treatments. This article has given an overview of the basics of these types of calculations, but there’s so much more to learn.
