Vacuum unit for emptying condenser

A prominent Italian power station replaced its system, based on steam ejectors with Gieffe System's liquid ring vacuum skid with total re-circulation of the service liquid, in order to reduce the emptying condenser time and improve the energy consumption. The installed system removes air and gas from the steam side of the condenser and it works up to 100 mbar(a) with a max capacity of 1.815 m³/h. It consists of liquid rings vacuum pump, mounted on a skid, including piping, separator tank, heat exchanger, valves, pressure transmitters, pressure gauge, temperature transmitters, temperature gauge and junction box.
