Aim: The aim of the course is to give an introduction to chemical
engineering concepts that are used in the chemical, biotechnological, and
the pharmaceutical industry. This introductory course will make the student able to
understand and sketch flowsheets for chemical plants
calculate size, composition, temperature and pressure of streams in chemical plants
calculate energy transfer in systems with pumps, turbines and in pipes
understand the fundamental principles behind a number of important types
of chemical process equipment and to get a general knowledge of such equipment
make quantitative calculations to design process equipment and to predict
performance and capacity of existing equipment when operating conditions are
changed
get a better understanding of the basic features for a number of important chemical engineering operations through experimental exercises. |
Contents: The course is extended over two semesters and combines theory,
experimental exercises and a major course problem. Systematic mass and energy balances for chemical processes with and without chemical reaction.
Stage processes exemplified by absorption columns. Applications of phase equilibria, bubblepoint and dew point calculations in multicomponent
systems. Design of distillation columns.
Chemical reactions. Yield, selectivity. Atomic balances for systems with
several chemical reactions.
Thermodynamic properties (heat capacity, heat of reaction etc.) Combustion
processes.
Examples: A number of typical problems from industrial processes are
presented to illustrate practical applications and to form a background for understanding the quantitative methods described in the course. Practical examples on solution of environmental problems.
Experimental exercises in groups of two on technical equipment including
absorption and distillation. Written reports must be handed in before the
end of the examination period.
Flow: The mechanical energy balance, flow of gases and liquids, calculation
of friction losses in pipe systems. Pumps, and turbines. Design
of pipe systems. Particle motion. Flow through particle layers.
Fluidization.
Heat transfer: Heat transfer by conduction and convection. Condensation.
Heat exchange and design of heat exchangers. Evaporation.
Mass transfer: Differential mass balances. Batch distillation. Diffusion.
Rate dependent mass transfer operations (absorption, stripping). Operations
involving heat and mass transfer (drying).
Experimental exercises in groups of two on technical equipment including
absorption and distillation. Written reports must be handed in before the
end of the 14-week period, autumn.
Solving a major course problem. |
