  • Patent number: 11549646
    Abstract: The invention primarily concerns a facility for storing and cooling a liquefied gas, for example a liquefied natural gas, the facility comprising at least one tank configured to contain the liquefied gas, a closed cooling circuit configured to be supplied with liquefied gas in the liquid state coming from the tank, at least one injection member configured for reinjecting cooled liquefied gas into the tank, the facility being characterized in that it comprises at least one connection line configured to recover a cooled gas from at least one remote container that is separate and independent from the facility.

  • Publication number: 20220275999
    Abstract: Disclosed is a refrigeration and/or liquefaction method using a system that includes a low-temperature refrigeration device comprising a working circuit which forms a loop and contains a working fluid, the working circuit forming a cycle comprising, connected in series: a compression mechanism, a cooling mechanism, an expansion mechanism and a heating mechanism the refrigeration device further comprising a cooling exchanger for extracting heat from the useful fluid stream by exchanging heat with the working fluid flowing in the working circuit, the system comprising a pipe through which the useful fluid stream flows in the cooling exchanger, the method comprising a cooling step in which the refrigeration device is in a first operating mode for cooling the cooling exchanger while a useful fluid stream flows in the cooling exchanger, the method comprising, after said cooling step, a step of cleaning impurities that have solidified in the cooling exchanger, characterized in that during the cleaning step, the ref

  • Publication number: 20220268516
    Abstract: Disclosed is a low-temperature refrigeration device comprising a working circuit that forms a loop and contains a working fluid, the device further comprising a cooling exchanger for extracting heat from at least one member by exchanging heat with the working fluid, the working circuit forming a cycle comprising, connected in series: a compression mechanism, a cooling mechanism, an expansion mechanism and a heating mechanism, wherein the mechanism for cooling the working fluid and the heating mechanism comprise a common heat exchanger in which the working fluid flows in opposite directions in two separate transit portions of the circuit according to whether it is cooled or heated, the device being designed to ensure equal mass flow rates in the two transit portions in the common heat exchanger, the device also comprising a bypass for bypassing one of the two transit portions, said bypass comprising a bypass valve which, in the open state, changes the mass flow rate in one of the two transit portions.

  • Publication number: 20220090854
    Abstract: A liquefied gas cooling apparatus including: a gas flow path for carrying a liquefied gas that is liquefied by cooling; and a refrigeration unit including a refrigerating cycle formed by a compressor, a cooling unit, and an expander. The compressor is driven through an electric motor contained in a sealed housing together with a compressor mechanism.
