Fluid Separations

In the lecture Fluid Separations several thermal unit operations are covered. The lecture is build upon the knowledge gained in the lecture “Introduction to Fluid Separation”. This knowledge is refreshed, deepened and extended by considering selected issues of fluid separation operations. During the tutorials, this knowledge is applied to several practically relevant tasks and thus memorized.

Current information are available on Moodle: Moodle FS
