CO2 saving processes
Organic Rankine Cycle (ORC) Module
GEA offers gas cleaning and energy recovery systems that employ ORC (Organic Rankine Cycle) technology, proven to be the most efficient solution for energy production.
The working principle of the Organic Rankine Cycle is the pumping of a working fluid into a superheater where it is evaporated, passed first through a turbine and then through a condenser heat exchanger where it is finally re-condensed.
The water leaving the ORC module condenser is cooled down by dissipating the heat to ambient air in a closed circuit through adiabatic or dry air coolers.
In the ORC module, the organic carrier fluid (organic substances with low boiling points and high vapor pressure) from the WHRU initially passes a further heat exchange step and then evaporates in the super heater and evaporator, driving a turbine with a coupled generator to produce electricity.
ORC energy recovery systems produce economical electricity or generate compressed air production for its use further in the production process.
Moreover, this solution contributes to the reduction of the entire CO2 footprint, since it generates no additional CO2 emissions.
Key features
- ORC technology works at low pressures and temperatures in contrast to other solutions
- High efficiency of the entire production system - approx. 25% of the exhaust heat is used
- High serviceability
- High flexibility of the various modules, ideal for retrofitting in narrow spaces
- Quick ROI (Return of Investment), sustainable reduction of energy costs
