Aim

The aim of the course is to train students to use process integration methods and tools necessary for identifying and designing efficient energy system solutions for the process industry that contribute to sustainable development. Technical systems encountered in the course include heat exchanger networks, boilers, heat pumps and combined heat and power systems. Besides technical issues, the course also covers methods for assessing the current and future economic and CO2 footprint performance of changes to industrial energy systems subject to uncertainty with respect to process conditions as well as future energy market conditions.

Literature

Compendium produced at the Division of Energy Technology, available in Canvas

For further reading, the book “Pinch Analysis and Process Integration: A User Guide on Process Integration for the Efficient Use of Energy” by I.C. Kemp is recommended. The book is available as an e-book from Chalmers library. Selected chapters are available in Canvas.

Changes made since the last occasion

Based on the course evaluation from the 2023 course offering, some course content has been removed or modified compared to 2023:

  • Some concepts related to Advanced Targeting (in particular Area Targeting and Capital Cost Targeting) have been revised and simplified
  • Network Relaxation (theory and exercise) has been dropped
  • Absorption heat pumps are no longer covered in detail
  • The compulsory project assignment related to the Renova Waste-to-Energy plant has been removed. Some of the content of the this project has been retained as an Exercise (E5), primarily the content related to energy performance of the plant.

 

Learning objectives and syllabus

Learning objectives:

  1. identify the major equipment units in an industrial steam network, and perform mass and energy balances calculations for such systems
  2. calculate energy flows and relevant performance indicators for process utility boilers, heat pumps, and combined heat and power (CHP) units
  3. determine the pinch temperature and the minimum heating and cooling requirements for a given industrial process and a given value of minimum acceptable temperature difference for heat exchanging
  4. determine target values for the number of heat exchanger units, the heat exchanger network surface area, and the investment cost for a heat exchanger network that meets the above energy targets, and analyse the impact of choice of minimum temperature difference for heat exchanging on these energy and cost targets (supertargeting)
  5. design a heat exchanger network for maximum heat recovery for a given new (greenfield) process
  6. identify and quantify inefficiencies (pinch violations) in the heat exchanger network of an existing process and suggest design modifications to reduce the heating and cooling demands of the existing network (retrofit)
  7. identify opportunities for energy-efficient integration of heat pumps and CHP units at an industrial process site as well as the potential for export of excess heat to a district heating system
  8. evaluate energy efficiency measures in industrial processes with respect to reduction of energy usage, greenhouse gas emissions and energy costs, accounting for current and possible future energy market conditions.

Examination

The written 4-hour examination includes theory and problem solving (with non-comprehensive calculations). The examination will be conducted in English. The standard Chalmers grade scale is used (Fail, 3, 4, 5).

The regular examination is scheduled on January 17th, 2025, from 08:30-12:30. The first re-sit examination is scheduled on April 15th, 2025, from 14:00-18:00. The second re-sit examination is scheduled on August 25th, 2025, from 8:30-12:30.

Completed and approved reports for the compulsory projects (P1-P3) are a course requirement as well as attendance of the industrial process site study visit. For submission deadlines, see the course schedule.
