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, combined heat and power systems, and thermal separation units. Besides technical and economic issues,  the course also covers the role of industrial process energy systems for meeting greenhouse gas emissions reduction targets. The course also introduces a method to identify the cost-optimal mix of different process heating technologies to satisfy a given process steam demand and for analysing how future energy policy instruments will influence this optimal solution.

Learning outcomes (after completion of the course the student should be able to)

  • calculate energy conversion performance characteristics for process utility boilers, heat pumps, and combined heat and power (CHP) units based on steam turbine or gas turbine cycles, for given energy conversion process parameters
  • 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
  • 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)
  • design a heat exchanger network for maximum heat recovery for a given new (greenfield) process and improve this design by relaxation of the requirement for maximum heat recovery
  • 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)
  • identify opportunities and quantify the potential for integration of high-efficiency energy conversion technologies and advanced utility systems (heat pumps, combined heat and power units, district heating) at an industrial process site
  • evaluate designs of new heat exchanger networks, retrofit modifications of existing heat exchanger networks and the integration of heat pumps, combined heat and power units and thermal separation plants with respect to energy efficiency, greenhouse gas emissions and economic performance
  • identify the cost-optimal mix of technologies for satisfying an industrial process heat demand with given load characteristics, accounting for current and possible future energy market conditions, including costs associated with emissions of greenhouse gases

Content

The course contains the following parts:
Introduction to industrial process energy systems: Basic concepts and illustrating example from the pulping industry.
Process integration: Basics of process integration methodologies with emphasis on pinch analysis (Pinch temperature, minimum process heating and cooling requirements, composite curves and grand composite curve, utility targeting, targeting for minimum number of heat exchanger units, and heat exchanger surface area costs). Design of heat exchanger networks for maximum heat recovery and network relaxation. Process integration principles for high-efficiency energy conversion technologies and advanced utility systems (heat pumps, combined heat and power units, district heating). Process integration methodologies for retrofit applications in existing industrial energy systems. Energy efficiency and economic performance evaluation of process integration measures.
Energy conversion technologies in industrial energy systems: Overview of utility boilers, heat pumps, steam turbine combined heat and power (CHP) and gas turbine CHP. Characteristics of heat pumps and CHP units (performance, investment costs). Optimization of size and various design parameters based on process integration principles. Methodology for identifying the cost-optimal mix of technologies for satisfying a process heat demand, accounting for heat load variation over the course of the year.
Greenhouse gas emissions consequences of energy efficiency measures in industry: Greenhouse gas emissions from industrial energy systems. Optimisation of industrial energy systems considering future costs associated with greenhouse gas emissions.

Organisation

The course includes lectures, compulsory and non-compulsory exercise projects, and one industrial laboratory session

Literature

Course book produced at the Division of Energy Technology, on sale at Cremona (Chalmers student litterature bookstore).
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.

Examination including compulsory elements

Written examination on theory and calculations. Fail-3-4-5 grading system. Completed and approved exercise project and laboratory reports are also a course requirement.

The course examiner may assess individual students in other ways than what is stated above if there are special reasons for doing so, for example if a student has a decision from Chalmers on educational support due to disability.
