Patent number: 7617701Abstract: In a process for producing a mixture containing at least 10% carbon monoxide (73) by cryogenic separation of a feed gas containing at least carbon monoxide, hydrogen and methane, the feed gas (1) is separated to produce a first gas enriched in hydrogen (71), the feed gas is scrubbed in a methane wash column (7), a carbon monoxide enriched stream (13) from the bottom of the methane wash column is separated (19) to produce a stream further enriched in carbon monoxide (23), the stream further enriched in carbon monoxide is separated to form a carbon monoxide rich stream (31,49) and a liquid methane stream (27), at least part (72) of the carbon monoxide rich stream is mixed with the first gas enriched in hydrogen to form the mixture containing at least 10% carbon monoxide as a product stream.Type: GrantFiled: April 7, 2004Date of Patent: November 17, 2009Assignee: L'Air Liquide, Societe Anonyme a Directoire et Conseil de Surveillance pour l'Etude et l'Exploitation des Procedes Georges ClaudeInventors: Jean Billy, Natacha Haik-Beraud, Jean Gallarda, Franck Wegrzyn

Patent number: 7464012Abstract: Process simulators, including a novel process simulator that utilizes simplified mathematical correlations to predict the performance of equipment or subsystems in a process unit. The process simulator comprises a process correlation that is a mathematical response model for a discrete process system in a process unit. The process correlation is developed by obtaining operating data over a range of operating conditions of the process unit and regressing the operating data to form the mathematical response model. The process simulator calculates a number of output parameters using a number of input parameters. The process simulator outputs the output parameters so they can be used by operating personnel to evaluate the current operations of the process plant and make operating decisions.Type: GrantFiled: November 14, 2005Date of Patent: December 9, 2008Assignee: L'Air Liquide, Societe Anonyme A Directoire et Conseil de Surveillance pour l'Etude et l'Exploitation des Procedes Georges ClaudeInventors: Jean Gallarda, Franck Wegrzyn, Antoine Hernandez, Frederic Bonne, Jan Cobbaut

Patent number: 6098424Abstract: A process and plant for the combined production of carbon monoxide and an ammonia synthesis from a feed gas mixture containing essentially hydrogen, carbon monoxide and other constituents including methane. The process comprises subjecting the feed gas mixture at high pressure to partial condensation through a heat exchanger followed by separation to produce an impure hydrogen flow and a condensed fraction rich in carbon monoxide. The carbon monoxide is cryogenically purified from the condensed fraction by separation and removal of dissolved hydrogen. The hydrogen is sent to a washing column, and is then cryogenically purified by washing with nitrogen in the washing column while drawing off a liquid fraction rich in carbon monoxide at the base of the washing column. An ammonia synthesis mixture is produced by adding a nitrogen supplement taken from a high-pressure nitrogen stream, and from the hydrogen flow produced at the head of the washing column.Type: GrantFiled: February 22, 1999Date of Patent: August 8, 2000Assignee: L'Air Liquide, Societe Anonyme pour l'Etude et l'Exploitation des Procedes Georges ClaudeInventors: Jean Gallarda, Franck Wegrzyn
