Reactor design uses information, knowledge, andexperience from a variety of areas: thermodynamics,

chemical kinetics, fluid mechanics, heat transfer, mass

transfer, and economics. Chemical reaction

engineering is the synthesis of all these factors with theaim of properly designing a chemical reactor.

Levenspiel, 1999


3/16

The study of chemical reaction engineering (CRE)

combines the study of

chemical kineticswith

the reactors in which the reactions occur.

Chemical kinetics and reactor design

are at the heart of producing almost all industrialchemicals.

It is primarily a knowledge of chemical kinetics andreactor design that distinguishes the chemical

engineer from other engineers

Fogler, 2006

Kinetics or how fast things happen.If very fast, then equilibrium tells whatwill leave the reactor. If not so fast,

then the rate of chemical reaction, and

maybe heat and mass transfer too, will

determine what will happen.

Contacting pattern or howmaterials flow through and contacteach other in the reactor, how early or

late they mix, their clumpiness or state

of aggregation. By their very nature

some materials are very clumpy (for

instance, solids and noncoalescing

liquid droplets.

Output = f(input, kinetics, contacting)
