Our company has been commissioned by Turboden S.p.A. to contribute to the design of the entire geothermal system for a 10 MWe net capacity geothermal power plant near Velika Ciglena, Croatia. Our tasks included the connection of the two extraction wells to the ORC power plant, the proper separation of the geothermal medium and the steam and non-condensable gases, and close cooperation with the plant technology manufacturer for the integration of the two systems. The cooled medium is injected back into two wells.
