Patent number: 10690406Abstract: The invention relates to a method for low-temperature cooling/liquefaction of a working fluid, in particular a working fluid including helium or consisting of pure helium by means of a refrigerator/liquefier that includes a working circuit provided with a compressor station and a cold box. The refrigerator/liquefier subjects the working gas within the working circuit to a cycle that includes, in series: compressing the working fluid within the compressor station, cooling and decompressing the working fluid in the cold box, and heating the working fluid with a view to the return thereof to the compressor station. The compressor station includes one or more compression levels, each one using one or more compressors mounted on landings.Type: GrantFiled: November 4, 2010Date of Patent: June 23, 2020Assignee: L'Air Liquide Societe Anonyme Pour L'Etude Et L'Exploitation Des Procedes Georges ClaudeInventors: Jean-Marc Bernhardt, Frederic Andrieu, Franck Delcayre, Fabien Durand, Veronique Grabie

Patent number: 7299642Abstract: The invention relates to an exchanger, advantageously a plate exchanger, comprising counter-current parallel exchange sections (8,9). According to the invention, the exchange section for the water (8) has an essentially constant cross-section, whereas the exchange section (9) for the cryogen has a reduced inlet region (9a) enabling the possible formation of ice (10) in the water passage (8) to be concentrated on a small volume, without blocking said water passage. The invention can especially be applied to the supply of gaseous hydrogen stored in a liquid form to an on-board power generating device in a vehicle.Type: GrantFiled: May 18, 2004Date of Patent: November 27, 2007Assignee: L'Air Liquide, Societe Anonyme a Directoire et Conseil de Surveillance pour l'Etude et l'Exploitation des Procedes Georges ClaudeInventors: Robert Moracchioli, Pierre Briend, Véronique Grabie, Jacques Chabanne
