Modelling of Separation Process

Description

Provides an understanding of simple model development, transfer functions, block diagram representation and analysis, and simple control systems. Most of the model development is based on simple unit operations and separation processes. Also provides students with the fundamentals necessary to design or evaluate a broad range of separation processes.
