Chemical Reaction Engineering 2: Heterogeneous Reactors

Chemical Reaction Engineering 2: Heterogeneous Reactors. Instructor: Prof. K. Krishnaiah, Department of Chemical Engineering, IIT Madras. In simple terms, Chemical Engineering deals with the production of a variety of chemicals on large scale. Large scale production is associated with the engineering problems such as fluid flow, heat and mass transfer, mixing and all types of unit operations. These chemicals are produced through chemical reactions in a vessel called Chemical Reactor. Chemical Reactor is known as the heart of any chemical plant since the new chemicals are produced only in this vessel and the economics of the entire plant depends on the design of reactor.

Chemical Reaction Engineering (CRE) deals with the design of Chemical Reactors to produce chemicals. The design of Chemical Reactors is based on a few simple and useful concepts. Though the concepts are simple, it is not easy for the students to develop a feeling for these concepts unless the teacher explains by giving different day to day examples with which the students are familiar with.
