KE2010 Industrial Energy Processes 7.5 credits

Industriella energiprocesser

Energy conversion systems are something that all people are dependent upon for transports, heating, household appliances, etc. The energy systems of the world are under a steady change and the major challenge today is how to combine sustainability with increased primary energy consumption globally. The special attention is on the close relationship between the use of primary energy and human-induced climate change.

In Sweden, the industrial energy system consume somewhat more than a third of the energy (final use) and the industrial sector is the second emitter of fossil carbon dioxide after the transport sector. The supply and use of energy has become an increasingly strategic issue for energy intensive industrial companies due to increased primary energy prices globally and policy instruments intended to mitigate the use of fossil fuels (carbon taxes, energy taxes, etc.). 

This course is covering advanced applied thermodynamics of importance for energy processes in heavy industries. During the course you will learn about technical, economic and, to some extent, environmental characteristics of real energy processes. The main part of the course is attributed to theory and problem solving within the field of technical thermodynamics.

Learning outcomes

After finished course, you should be able to:

  • Analyse the technical performance for industrial energy processes in industrial scale with the help of thermodynamic relationships.
  • Calculate combustion reactions and heat yield for different fuels.
  • Perform thermodynamic calculations on thermal power and combined heat and power cycles, e.g. steam cycles, combined cycles, and stationary motors.
  • Estimate the potential for energy efficiency by utilizing process integration (also referred to as pinch analysis) including heat exchanging, heat pumping, and waste heat recovery.
  • Apply relevant system boundaries to energy-related problems.
  • Analyse the performance of energy conversion systems in relation to ideal systems and with this as a starting point suggest improvements.
  • Evaluate the economic consequences of different energy solutions.

Course main content

An overview of energy consumption and energy conversion systems in the world is presented in the beginning of the course. The concepts open and closed systems are studied together with system boundaries and their relevance for thermodynamic calculations. A part of this is the difference between internal energy and enthalpy.

Energy conversion in theoretical and real processes is analysed at lectures and exercises (tutorials) and the concept exergy is introduced. Exergy is a tool used for ease of understanding of what is theoretically achievable in energy conversion systems.

Different types of energy technologies utilised in industrial processes are discussed. When the homework assignment is presented, some basic economic prerequisites for energy systems are introduced. One part of the economic considerations that are of increasing importance to industries is energy efficiency measures, often examined by so called pinch analysis. All the teaching/learning activities that involve calculations are covered during the exercises (tutorials).

Disposition

A full day study visit is planned during the course.

Eligibility

Admission requirements for programme students at KTH:
At least 150 credits from grades 1, 2 and 3 of which at least 110 credits from years 1 and 2, and bachelor's work must be completed, within a programme that includes:
75 university credits (hp) in chemistry or chemical engineering, 20 university credits (hp) in mathematics and 6 university credits (hp) in computer science or corresponding.

Admission requirements for independent students:
75 university credits (hp) in chemistry or chemical engineering, 20 university credits (hp) in mathematics and 6 university credits (hp) in computer science or corresponding. Documented proficiency in English corresponding to English B.

Prerequisites

Knowledge equivalent to the course KE1030 Transport Phenomena and Engineering Thermodynamics.

Literature

"Fundamentals of Engineering Thermodynamics" (SIVersion), by Moran & Shapiro (6th edition), John Wiley & Sons.

Additional material will be distributed or sold on lectures and exercises (tutorials).

Examination

  • BER1 - Calculation Task, 3.0 credits, grade scale: P, F
  • TEN1 - Examination, 4.5 credits, grade scale: A, B, C, D, E, FX, F

The two examination components are evaluated and reported separately. The homework assignment includes reported calculations, a presentation and a reflective report about your own contributions in relation to the project as a whole.

Over the course, two intermediate tests that together could give up to 20 credits are offered. If 12 or more credits are achieved in these tests, full score will automatically be given on one specified problem at the exam. This problem should therefore not be solved.

Requirements for final grade

Passed examination (TEN1; 4,5 credits)

Passed homework assignment including presentation and supplementary reflecting report (BER1; 3 credits)

The grades A to F are given as the final grade after the student has passed both examination parts.
