Course content

Topics from thermodynamics and physical chemistry: State variables, ideal gas, equations of state, work and heat, Laws of thermodynamics, internal energy, enthalpy, entropy, Gibbs energy, equilibrium. Topics from process engineering: The balance principle. Mass balances. Mass balances with chemical reactions. Energy balances (2nd law of thermodynamics). Heat exchange. Mechanical work (compression and expansion). Work from heat. Process modelling using Python.

Learning outcome

At the end of the subject the students should:
- Know how mass and energy balances are formulated in a stationary system.
- Use the 1. and 2. law of thermodynamics together with mass balances and equilibrium relations to find the equilibrium product composition after a reactor.
- Formulate and solve an equation system of mass and energy balances for a stationary process with reaction, separation and recirculation.
- Do quantitative calculations of mass and energy balances in stationary chemical processes.
- Do simple simulations of mass and energy balances in stationary chemical processes.
- Calculate the necessary area of a heat exchanger.
- Calculate the heating/cooling effect and energy consumption in a heat pump or refrigerator.
- Use energy and mass balances to do stationary calculations of turbines, pumps, valves, heat exchangers, splits, mixing units, heat exchangers, refrigerators and reactors.
- Have detailed knowledge of at least one chemical process from the Norwegian process industry.
