Process integration and pinch analysis (TSM_ProcInt)

Against the background of rising energy prices, incentive taxes and ecological requirements, increasing importance is being attached to reducing the energy requirements of industry. The key to higher energy efficiency and cost-efficiency in thermal processes is the energy integration of processes with the aid of pinch analysis. This is characterized by a systematic approach which can be applied to establish the best system design and the optimum energy input from the economic viewpoint. From the results of the analysis, it is possible to derive measures for heat recovery and an improved energy supply in the context of strategic planning.
In this module, students learn the fundamental methods of the energy integration of processes with the aid of pinch analysis. After completing the module, they are in a position to conduct pinch analyses by themselves for "straightforward" industrial processes and to answer the following questions: how large is the energy requirement if an existing plant were to be fully-optimized? Where is the economic optimum for the investment and energy costs? How can this optimum state be achieved? They can then support industrial companies in sustainable development and in the reduction of CO2 emissions, since reducing energy requirements goes hand in hand with increasing cost-efficiency.

Compétences préalables

Students should have a keen interest in process engineering and energy engineering issues. Attendance of the module requires prior knowledge of engineering thermodynamics. This includes, in particular:

  • the first law (and ideally also the second law) of thermodynamics and its application to flow processes and energy conversion systems such as heat engines, heat pumps or cooling systems
  • a good understanding of the concept of enthalpy for pure substances
  • the theory of heat transfer:  fundamental laws of heat transfer; mean logarithmic temperature difference of co-current and counter-current heat exchangers
  • the calculation of mass, component and energy balances for common industrial unit operations and processes

Prior knowledge of thermal process engineering and the energy integration of processes is desirable but not absolutely essential for attending the module.

Objectifs d'apprentissage

The student

  • understands the "nature/philosophy" of process design as well as the energy integration of processes and pinch analysis (onion model, targets before design).
  • can complete the mass, component and energy balance for industrial processes with several components and phases and masters the fundamental laws of the thermodynamics for multi-component systems (only ideal two-component systems, e.g. humid air).
  • masters the thermodynamically correct assessment of energy conversion systems and the fundamentals of heat transfer with regard to the energy integration of processes and pinch analysis.
  • is in a position to determine the energy targets, heat transfer area targets and cost targets of processes (continuous and non-continuous) using the fundamental methods of pinch analysis (problem table algorithm, composite curves, grand composite curve and cost curves, etc.).
  • is familiar with and understands the "golden rules" of pinch analysis plus the rules for the design of heat exchanger networks, and is able to apply these for practical cases. He/she can, additionally, optimize heat exchanger networks.
  • is able to correctly place utilities such as steam and cooling water systems and also energy conversion systems like heat pumps, combined heat and power generation systems, etc. in a process.
  • after completing the module, is in a position to correctly perform the energy modeling of a process and conduct the pinch analysis independently with the aid of software, and to work out measures for increasing efficiency.
