Agitation and Fluid Mixing Technology

Many industrial processes rely on effective agitation and mixing of fluids. The application of agitators cover the areas of mining, hydrometallurgy, biol-ogy, petroleum, food, pulp and paper, pharmaceutical and chemical process industry. In particular, in these industries we find typical chemical reaction engineering processes like fermentation, waste water treatment, hydrogenation, polymerization, crystallization, flue gas desulfurization, etc [65, 21]. 

Generally, agitation refers to forcing a fluid by mechanical means to flow in a vessel. Mixing usually implies the taking of two or more separate phases, or two fluids, and causing them to be randomly distributed through one another. 

There are many ways to obtain mixing in a vessel. This chapter focuses on the turbulent impeller type of mixers, as they are frequently applied in the chemical process industries.
