| Aim: The course form an introduction to chemical engineering and will convey a basic knowledge of a number of important chemical engineering concepts that will make the student able to understand and sketch flowsheets for chemical plants - to calculate size, composition, temperature and pressure of streams in chemical plants - to calculate energy transfer in pumps, compressors, turbines and in pipe systems - to understand the fundamental principles behind a number of important types of chemical process equipment and to get general knowledge of such equipment - to make quantitative calcultations to design process equipment and to predict performance and capacity of existing equipment when operating conditions are changed - to get better understanding of the basic features for a number of important chemical engineering operations through experimental exercises. |
Contents: Part 1:
14 weeks period, autumn. Mass balances for systems without chemical reactions exemplified by single- and multistage extraction.
Stage processes exemplified by absorption columns. Applications of phase equilibria, bublepoint and dewpoint calculations in multicomponent systems. Design of destillation columns. Chemical reactions. Yield, selectivity. Atomic balances for systems with several chemical reactions. Energy balances for systems without or with 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. Descriptions and calculations of one or several important chemical processes. Practical examples on solution of environmental problems.
Part 2:
Last 8 weeks of 14 week period, autumn. 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.
Part 3:
14 weeks period, spring.
Flow: The mechanical energy balance, flow of gases and liquids, calculation of friction losses in pipe systems. Pumps, compressors 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). |
