Patent number: 9733013Abstract: A compressed air stream is cooled in an exchanger to form a compressed cooled air stream. The stream is then cryogenically compressed in a first compressor to form a first pressurized gas stream. The first pressurized gas stream is further cooled in the exchanger, cryogenically compressed in a second compressor, and then it is cooled and partially liquefied. The cooled and partially liquefied product is then fed to a system of distillation columns. A liquid product is removed from the system of distillation columns. This product is then pressurized, vaporized and warmed in the exchanger to yield pressurized gaseous product.Type: GrantFiled: May 30, 2014Date of Patent: August 15, 2017Assignee: L'Air Liquide Société Anonyme Pour L'Étude Et L'Exploitation Des Procedes Georges ClaudeInventors: Jean-Renaud Brugerolle, Bao Ha
