Natural Gas Processing and Transportation

This is the study programme for 2019/2020. It is subject to change.

This course addresses processing and transportation concepts for natural gas and natural gas liquids, with a strong emphasis on the computational aspects. Natural gas chemical composition is the key in most predictive methods. These methods are of such a nature that insight into numerical mathematics and algorithm construction is necessary for their implementation.

Learning outcome

Upon completing this course, the student should have:
  • Detailed knowledge of how thermodynamic principles and material models (equations of state) interact to produce equations relating physical and thermodynamic properties to the chemical composition of natural gas, and of the numerical methods required to solve these equations.
  • Ability to manipulate mathematical expressions in order to reproduce the aforementioned equations, and to construct algorithms and implement the computer codes for obtaining numerical solutions.
  • Ability to prepare various technical information to go as input values in commercial software packages for process simulation.
  • A general capability to interpret the results from process calculations- and simulations in terms of their usefulness and limitations.


  • Thermodynamic relations, equations of state, vapour pressure curves, mixing rules;
  • Specific volume, residual functions, K-values, Rachford-Rice equation;
  • Phase equilibrium, 2-phase flash, dew- and bubble point flash, critical point, phase envelope;
  • Compression, pressure drop, heat exchange, evaporation and condensation;
  • Flow sheet calculations, process simulations.
