Lecture Semester

5^th semester (autumn)

The student's learning outcomes after completing the course

Knowledge: The students know how to

• describe energy flow in process and energy systems
• perform calculations such as mass and energy balances for several of the course topics

Skills: The students are able to

• conduct unsophisticated HAZOP analyses
• conduct energy analyses, dimension simple thermal processes, select the working fluid and calculate energy use

Competence: The students are able to

• communicate professionally with others with the similar background and with expert environments
• use their theoretical knowledge to optimize energy use
• read and understand industrial flowcharts

Content

The following topics will be introduced:

• Mass and energy balances
• Phase transitions
• Review of various unit operations related to energy turnover
• Combustion processes
• Analysis of energy flows in distillation columns
• Pumps, turbines and compressors
• Cost estimation of process plants
• Flowcharts
• Safety and HAZOP studies
• Immaterial property rights related to the process industry
• Using thermodynamic analysis (Pinch Technology) and heuristic rules for the design of industrial processes
• Heat transfer and heat exchangers
• Exergy analysis
• District heating systems
• Renewable energy processes; behavior, energy currents and potentials for solar, wind, wave, water, tidal, salt gradient, geothermal and bioenergy systems
• Transportation of natural gas, processing of natural gas, hydrates and hydrate formation
• Gas explosions and safety aspects of the transportation of gas
• Integration of new energy carriers and sources; production, transportation and end use, focusing on the use of hydrogen and fuel cells
• Processes for CO2 capture, including absorption processes

Forms of teaching and learning

The course is taught through lectures, self-study, laboratory work, preparation of technical reports and compulsory exercises. The focus is on academic writing of reports. The students are expected to participate in site visits. The topics covered at company visits can be subject to examination.

The course aims to introduce energy flow in process and energy systems, and train the solving of energy-related problems.
Knowledge is required of environmental, health and safety measures when carrying out laboratory work, and of relevant theory related to the specific laboratory task.

The course is regularly taught in Norwegian, but may be taught in English when needed.
Textbooks, exercises and some lectures are in English.

Coursework requirements - conditions for taking the exam

Participation in laboratory exercises
Participation in site visits
Exercises (50% have to be passed)

Further details are given in the semester plan.
All coursework must have been passed and approved before students can sit the exam.

Examination

A 3-hour written exam.
In accordance with given criteria a selection of technical reports, presentations of reports, and laboratory exercises are to be submitted at the exam.

Permitted aids are formula collections and a calculator.

An overall grade is given for both the written exam and submitted reports and assignments.
The grading system A-F is used, with A as the best and E as the lowest pass mark. F means ”failed”.

Course evaluation

The course is evaluated continuously throughout the semester with methods agreed upon by the teacher (s) and students.
Written final evaluation of the course.
