Patent number: 11560308Abstract: Method and plant for generating a synthesis gas which consists mainly of carbon monoxide and hydrogen and has been freed of acid gases, proceeding from a hydrocarbonaceous fuel, and air and steam, wherein low-temperature fractionation separates air into an oxygen stream, a tail gas stream and a nitrogen stream, wherein the tail gas stream and the nitrogen stream are at ambient temperature and the nitrogen stream is at elevated pressure, wherein the hydrocarbonaceous fuel, having been mixed with the oxygen stream and steam at elevated temperature and elevated pressure, is converted to a synthesis gas by a method known to those skilled in the art, and wherein acid gas is subsequently separated therefrom by low-temperature absorption in an absorption column, wherein the nitrogen stream generated in the fractionation of air is passed through and simultaneously cooled in an expansion turbine and then used to cool either the absorbent or the coolant circulating in the coolant circuit of the compression refrigeratioType: GrantFiled: November 20, 2017Date of Patent: January 24, 2023Assignee: L'Air Liquide, Societe Anonyme Pour L'Etude Et L'Exploitation Des Procedes Georges ClaudeInventors: Lucie Chaubet, Frederic Bonne, Camille Bouet, Holger Schlichting, Marc Wagner

Publication number: 20180017321Abstract: The method for the production of nitrogen can include the steps of a) providing a waste nitrogen gas stream at a first pressure called low pressure, wherein the waste nitrogen gas originates from a low pressure column of a cryogenic air separation unit; b)compressing the waste nitrogen gas stream to a second pressure in a waste nitrogen compressor to produce a pressurized nitrogen stream; and c) introducing the pressurized nitrogen stream to a nitrogen generator under conditions effective for producing a purified nitrogen product, wherein the purified nitrogen product has a higher concentration of nitrogen as compared to the pressurized nitrogen stream.Type: ApplicationFiled: July 12, 2017Publication date: January 18, 2018Applicant: L'Air Liquide, Societe Anonyme pour I'Etude et I'Exploitation des Procedes Georges ClaudeInventors: Michael A.

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
