Aim
The aim is to give basic knowledge of the physical-chemical basis for different separation methods and to apply these for selection and design of industrial separation processes

Knowledge and understanding
For a passing grade the student must

• be able to estimate which methods that are feasible for separation of a mixture from physical-chemical data for the compounds in the mixture

• be able to understand how various parameters influence the capacity, degree of separation and energy efficiency of various separation process

Skills and abilities
For a passing grade the student must

• be able to execute material and energy balances combined with phase equilibria for design of various separation processes comprising equipment size, capacity, degree of separation and energy efficiency

• present the solution of a separation problem in a technical PM intended to be an internal technical report within a company

Contents
The course deals with with various methods for separation of compounds in gases, liquids or solids materials

The following issues are treated:
The physical-chemical principles for the following separation processes: Filtration, Membrane Processes, Adsorption, Chromatography, Ion Exchange, Evaporation, Drying, Crystallisation, Extraction, Leaching, Absorption and Distillation. For some of these only the principles are treated while some selected are treated more in detail.

Principles for selection of separation process:
Which separation processes that are used today. Examples will be given from chemical and biotechnical process industry and from the environmental sector.
Methods for determination of important design parameters, such as purity, yield, energy demand etc for the following separation methods: filtration, membrane filtration, evaporation, distillation, adsorption/chromatography and drying.

Four project exercises treating different separation problems are performed to train the students in applying the acquired knowledge to separation problems in the chemical and biotechnical industry. Project 1 is presented both in written and orally and the other three in written.

Three laboratory studies focused on the design and handling of separation equipment and are related to calculation of the process performance

The engineering attitude to problem solving is stressed.
