A fuel gas delivery system is provided. The fuel gas delivery system includes a feed line configured to provide a natural gas stream and a cryocooler fluidly coupled to the feed line. The cryocooler is configured to condense the natural gas to provide a liquefied natural gas (LNG) stream and to freeze impurities contained in the natural gas stream. The frozen impurities are separated from said LNG stream. A first heat exchanger is fluidly coupled to the cryocooler and the first heat exchanger is configured to vaporize at least a portion of the LNG stream to provide compressed natural gas. A delivery line is configured to supply the compressed natural gas to an end user and a removal line is configured to remove the impurities from the fuel gas delivery system.

A high temperature superconducting (HTS) magnet coil disposed within a cryostat is configured with a thermo-siphon cooling system containing a liquid cryogen. The cooling system is configured to indirectly conduction cool the HTS magnet coil by nucleate boiling of the liquid cryogen that is circulated by the thermo-siphon in a cooling tube attached to a heat exchanger bonded to the outside surface of the HTS magnet coil. A supply dewar is configured with a re-condenser cryocooler coldhead to recondense boiloff vapors generated during the nucleate boiling process.

摘要:
A method for cooling a superconducting magnet enclosed in a cryostat includes introducing a gas into a cooling path in the cryostat from an input portion into a cooling path cooled by a refrigerator outside the cryostat. A heat exchanger inside the cryostat above the magnet cools the gas. The cooled gas flows through a magnet cooling tube contacting the magnet. The cooled gas removes heat from the magnet, and to the heat exchanger to re-cool and return to the superconducting magnet, thereby cooling and/or maintaining the magnet at a superconducting temperature.
