Reactors deal with several aspects of chemical engineering. A chemical reactor where many of the chemical processes occur.

The three most important factors to consider in a chemical reactor are:

• mass transfer
• heat transfer
• chemical kinetics

All three factors are important and interrelated. It is the job of a chemical engineer to ensure that a reaction proceeds with the highest efficiency, producing the purest product using the least possible amount of energy.
