Heat and Power Technology Heat and Power Technology
Main theme: Rational use of energy in industrial energy systems
Focus on Economy, Efficiency, Environment Emphasis on Process Integration & System perspective
Industrial Energy Systems
Heat and Power Technology Heat and Power Technology
This course provides method and tools for: • Energy efficiency analysis
–What are the minimum heating and cooling demands for a process plant? Pinch Analysis
• Design and retrofit of process utility and heat recovery systems –Heat exchanger networks –Process integration of heat pumps, cogeneration and
energy-intensive unit operations (e.g. evaporator trains) • Carbon footprint management
–Identification of cost-effective utility mix to meet process heat demand under given carbon emission constraints
Heat and Power Technology Heat and Power Technology
Approach: 15*2h lectures, 13*4h hands-on exercise projects, 1*4h Industrial Laboratory • Project 1: pinch analysis, cost targeting and design of a heat exchanger
network for energy recovery and effluent cooling at a TMP (Thermo Mechanical Pulp) plant (2*4h)
• Project 2: split GCC analysis for integration of thermal separation processes and gas turbine CHP (1*4h)
• Project 3: split GCC analysis for integration of MVR heat pumps, including economic performance (1*4h)
• Project 4: pinch analysis and retrofit of a pulp mill dryer plant (2*4h) • Project 5: investigation of HEN retrofit options using the matrix method
(1*4h) • Project 6: Assessing heat production investment options in an industrial
process energy system considering possible future increased costs associated with CO2 emissions (2*4h)

Major challenges
• 100+ students • Mixed backgrounds
• ChemE ↔ MechE • Chalmers ↔ EU ↔ ROW
• PPT boredom. How to avoid it? • No fancy math? Much of the
complexity is in making choices, establishing system boundaries, reading graphical insights?
• Builds on ability to switch between different perspectives. What is a HP? How does it work? How do we represent it in a GCC?
