  • Publication number: 20210254789
    Abstract: A method for storing and distributing liquefied hydrogen using an installation having a storage facility for liquid hydrogen, a source of gaseous hydrogen, a liquefier having an inlet connected to the source and an outlet connected to the liquid hydrogen storage facility, the storage facility having a liquid withdrawal pipe having an end connected to the liquid hydrogen storage facility and an end configured to be connected to at least one mobile tank, the method having a stage of liquefying gaseous hydrogen and a stage of transferring the liquefied hydrogen to the storage facility, wherein the liquefied hydrogen has a temperature below the bubble point of hydrogen at the storage pressure and further having a stage of transfer of liquid hydrogen directly to the tank at a temperature between the saturation temperature at the pressure of the liquid and a temperature above the solidification temperature of the hydrogen.

  • Publication number: 20200206686
    Abstract: A process for purifying a feed gas stream containing at least 90% of CO2, at least 20% RH and at least one impurity chosen from chlorinated, sulfur-bearing, nitrated or fluorinated compounds is provided. The process includes a) subjecting the feed gas stream to catalytic oxidation producing a stream containing at least one of HCl, NOx, SOx or hydrofluoric acid; b) maintaining the temperature of the gas stream above the highest value between the dew points of water and the acid(s) contained in the gas; c) removing at least a part of the acid impurities by bringing the gas stream into contact with a corrosion-resistant heat exchanger to condense the acid compounds while regulating the temperature of the gas stream exiting below the dew point of water; and d) separating the acid condensates with a corrosion-resistant separator in such a way as to produce a CO2-enriched gas stream.
