Processes & energy

Presentation

Programme (detailed contents):

-   the global context of production and processing energy

-   processes for power generation,

-   renewable energies : wind, solar and biogas,

-   steam power cycles: Carnot cycle with superheat, reheat and withdrawals (cycle with maximum theoretical efficiency). Application to nuclear plants. Cogeneration systems. Size and optimization of the plant (energy and exergy efficiency)

-   refrigeration cycles from reverse Carnot cycle without change of state to the real cycle of refrigerating machines with change of state.

-   the absorption chillers. Size and optimization of the plant (energy and exergy efficiency)

-   the gas liquefaction. Cycle at maximum theoretical efficiency, Linde and Claude cycles. Presentation facilities for liquefying air and separating components. Special facilities for hydrogen and helium.

Organisation:

Lectures, tutorials and lab work. This modules includes visiting of: a wind farm, a nuclear power plant (Golfech) and a landfill site (Montech)

Objectives

At the end of this module, the student will have understood and be able to explain (main concepts):

-  the world context of power-generating systems, which produces a net power output from a fossil, nuclear or renewable energy source.

-  the legal and technical context of the various forms of renewable energy (wind, solar photovoltaic, biomass ...),

-  the different thermodynamic cycles associated to the power generation systems, the refrigeration and heat pump systems and the gas liquefaction.

-  the use of energy and exergy balances for these thermodynamic systems in order to optimize their operation

The student will be able to:

-   design a given steam power plant, including the choice of working fluid temperatures, pressures and the determination of fluid working flows plus the pre-sizing of compressors and turbines

-   design a refrigeration system, including the choice of working fluid temperatures, pressures and the determination of fluid working flows plus the preliminary design of compressors and expansion devices,

-   design a gas liquefaction plant

-   participate in the implementation of a wind energy area development and a site photovoltaic,

-   participate in the implementation of a biogas network.

Needed prerequisite

Thermodynamics.

Form of assessment

The evaluation of outcome prior learning is made as a continuous training during the semester. According ot the teaching, the assessment will be different: as a written exam, an oral exam, a record, a written report, peers review...
