Definitions

  • Gas recovery is normally performed with the help of a gas buffer.
  • the quenching chamber is emptied into a gas buffer until the pressure is equalized in the quenching chamber and the gas buffer.
  • the gas buffer is generally a balloon and/or a pressure container. The balloon expands when filled. Since the gas is ultimately under atmospheric pressure in the balloon, the gas takes up a large volume and the filled balloon requires a great deal of space accordingly. Before the gas is fed back into the high-pressure container, it must be compressed from atmospheric pressure to the pressure prevailing in the high-pressure reservoir.
