  • Dust-laden wet gas treatment
    Patent number: 8388734
    Abstract: A method for producing a CO2-enriched gas from a feed gas comprising carbon dioxide (CO2), at least one component selected from H2, N2, CH4, CO, O2 and argon, water vapor, optionally impurities such as NOx and/or SOx , and a solid-particle concentration of between 0.01 and 100 mg/m3, wherein the feed gas is at least partially dried upstream of a PSA unit in order to prevent the solid particles from caking in the PSA unit is provided.
    Type: Grant
    Filed: June 15, 2009
    Date of Patent: March 5, 2013
    Assignee: L'Air Liquide Societe Anonyme pour l'Etude et l'Exploitation des Procedes Georges Claude
    Inventors: Christian Monereau, Arthur Darde, Anne Berthelemot
  • Repressurization of a VSA treating a gas mixture comprising a fuel
    Patent number: 8226744
    Abstract: A method for purifying or separating a gas mixture comprising at least one fuel, using a unit having at least one adsorber subjected to a pressure cycle comprising at least one step of placing under vacuum by means of a vacuum pump, wherein at least one adsorber and/or the vacuum pump, depressurized during the cycle, is repressurized at least partly by an external gas to said unit and not containing a sufficient quantity of oxidizer to create an inflammable mixture during this repressurization.
    Type: Grant
