MUMBAI, India, June 6 -- Intellectual Property India has published a patent application (202414086904 A) filed by L'Air Liquide, Societe Anonyme Pour L'Etude Et L'Exploitation Des Procedes Georges Claude, Paris, on Nov. 11, 2024, for 'process for separating waste gas from a ferrous metal production unit.'
Inventor(s) include Marty Pascal; Rodrigues Guillaume; and Madelaine Laurette.
The application for the patent was published on June 6, under issue no. 23/2025.
According to the abstract released by the Intellectual Property India: "A process for separating waste gas from a ferrous metal production unit uses a first adsorption unit (4) to separate the waste gas by pressure swing adsorption to produce a gas (5) depleted in carbon monoxide and hydrogen and enriched in CO2 relative to the waste gas, and a first gas (7) enriched in carbon monoxide and hydrogen and depleted in CO2 relative to the waste gas, a unit (CC) for separation by partial condensation and/or distillation, means for sending the CO2-enriched gas to the partial condensation and/or distillation separation unit (CC) to produce a CO2-rich fluid (14), a second adsorption unit (6), means for sending at least a portion of the CO-enriched gas for separation by temperature swing adsorption in the second adsorption unit (6) to form a gas (23) enriched in CO2 relative to the first CO-enriched gas at a first pressure, and a second gas (15) enriched in CO and hydrogen relative to the first CO-enriched gas, the second gas containing nitrogen, a unit (CB) for separation by partial condensation and/or washing and/or distillation, means for sending at least a portion of the CO and hydrogen enriched second gas (15) to the separation unit (CB) for separation therein to produce a gas (17) depleted in nitrogen and enriched in CO relative to the second gas."
