Teaching control into a mass transfer operations course

This work presents a discussion about including process control topics into the mass transfer operations course in the chemical engineering curriculum. This inclusion is a part of the changes in chemical engineering curriculum stated more than ten years ago at Universidad Nacional de Colombia, Medellín campus. The advantages and disadvantages of this change are exposed in brief, using as example the mass transfer course. The relevant aspects of teaching control systems for a mass transfer course are listed. The liquid-liquid extraction mass transfer process is used as an example to illustrate the mentioned topics.
