  • Patent number: 10690387
    Abstract: A system and a method for recovery and recycling of gases which are utilized in their liquid state as refrigerants in applications that require low temperatures, throughout various pressure ranges, from slightly above atmospheric pressures to pressures near the critical point for the particular gas. The system and method are based on closed-cycle cryocoolers and utilize the thermodynamic properties of the gas to achieve optimal liquefaction rates.
    Type: Grant
    Filed: August 7, 2015
    Date of Patent: June 23, 2020

  • Patent number: 8973397
    Abstract: A helium recovery plant adapted to filter, compress, and purify helium gas collected from one or more helium-using instruments, as well as to liquefy and redistribute the purified gas within a closed system. The recovery plant is adapted to match the purification and liquefaction rate of the system with the consumption rate of the coupled instruments. Additionally, the recovery plant is adapted to match the liquefaction rate of a liquefaction module with a boil-off rate of liquid helium within a Dewar thereof. The recovery plant is further adapted to recycle helium therein in an effort to achieve zero loss.
