Synopsis:

Classis from Equipment for diffusion separation processes are giving a basic knowledge of processes and equipments where gas or liquid mixture is been separated due to principals of physical-chemical equilibriums or on the basis of mass transfer mechanisms. They are used for concentrating of products from dilute solutions or in turn for purification of diluted gasses or liquid solutions.

Syllabus of tutorials:

1. Basic equations and quantities in mass transfer, phase equilibrium, molecular diffusion, convective mass transfer.

2. Absorption column calculation, differential balance, determination of column height.

3. Single continuous distillation of a binary mixture.

4. Expansion distillation (flash).

5. Rectification column, calculating the number of distillation trays.
