Course content

The course comprises selected industrial applications of industrial process systems and energy conversion processes, with emphasize on natural gas. Introductorily, an overview of important problems and challenges in Norwegian process industry is given. Then some selected applications are treated in more detail. These applications are natural gas processing, natural gas power plants and LNG-technology.
A general basis in boiling and condensations is given with emphasize on industrial heat exchangers is also provided. The course is thaught in close cooperation with relevant Norwegian Industry.

Learning outcome

The course provides the student with knowledge about:
- The natural gas value chain –from well to marked
- How to describe central process units and some of the main equipment in the chain
- The mathematical models used in PRO-II
- Processes for removal of H2S and CO2 from natural gas
- The elements of LNG chains with main focus on natural gas liquefaction technology
- Basic thermodynamic properties and characteristics of LNG
- Natural gas purification needs and quality specifications for LNG
- LNG plant block diagrams
- Process flow diagrams and principles for the major types of liquefaction processes
- Optimization of single mixed refrigerant processes.
- Cryogenic heat exchanger principles
- Gas turbine based power generation, with respect to unit operations involved and system integration
- Fluid flow in turbo machinery; compressors and turbines, as well to understanding how thermal energy is converted to work
- Steam production in Heat Recovery Steam Generators (HRSG)
- Operational characteristic of a gas turbine; compressor map, turbine map, choking conditions for pressure determination.
- Basic control of gas turbines.

The course gives the student insight about:
- Natural gas processing
- Production and handling of LNG
- Power generation and cogeneration with natural gas

Skills:
The course should enable the student to:
- Establish process simulation models for gas processing steps in the process simulator PRO-II
- Construction of heating/cooling curves of LNG processes by the use of PRO/II.
- The student shall be able to calculate an off-design and or part-load conditions of a gas turbine.
- How to calculate the steam production in HRSGs.

General competence:
The course should give the student:
- Insight in industrial processes based on thermodynamics and mass and heat transfer. Further, the student should develop skills in applying basic theory in solving engineering problems.

Learning methods and activities

Lectures, ordinary exercises and computer exercises with process simulation tool. 2/3 of the exercises must be accepted. Excursion to the Methanol factory at Tjeldbergodden, to SINTEF Multiphase flow laboratory at Tiller and to Statoil Research center at Rotvoll. The lectures and exercises may be held in English when students who do not speak Norwegian take the course. The exam will be in english only if the teaching has been given in english. Students are free to choose Norwegian or English for written assessments.

Further on evaluation

Portofolio assessment is the basis for the grade in the course. The portofolio includes a final written exam (70%) and three oral exams (each 10%). The result for the parts are given in %-scores, while the entire portofolio is assigned a letter grade.

If there is a re-sit examination, the examination form may be changed from written to oral.

For a re-take of an examination, all assessments during the course must be re-taken.

For a re-take of an examination, assignments shall not be re-taken. Assignment scores from first attempt will be used.

Specific conditions

Exam registration requires that class registration is approved in the same semester. Compulsory activities from previous semester may be approved by the department.
