Mass transfer operationsLaajuus (6 ECTS)

Objective

After completion of this course the student will have the knowledge on physical and technical basics, calculations and realization of mass transfer operations and processes.
-----
After completion of this course the student will be able to evaluate the ideality and non-ideality of binary mixture and knows how to calculate vapor liquid equilibrium of ideal mixtures and flash distillations. The student is able to generate different types of vapor liquid diagrams using simulation programs and compare them to experimental diagrams of literacy and one made in physical chemistry laboratory. The student will be able to select and calculate the theoretical number of stages, the height and the diameter of a distillation, absorption and extraction column. The student is familiar with the diagrams of extraction and is able to select an appropriate adsorbent, crystallizer and drier.
