WebThis lecture discusses Batch reactor, Completely stirred tank reactor and Plug flow reactor. The equations associated with them are derived.

WebAny reactor that can be described by the plug flow model, no matter what its structure, is called a plug flow reactor. Similarly, any reactor that follows the complete mixed assumption is a complete mixed reactor. In reality, there is no reactor that can meet either plug flow or complete mixed assumptions completely.
