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: "In a process for separating waste gas from a ferrous metal production unit, the waste gas (1) is compressed in a first compressor (C) and then separated by pressure swing adsorption (4) in an adsorption unit to produce a carbon monoxide-depleted and CO2- enriched gas (5) relative to the waste gas and a first carbon monoxide-enriched and CO2-depleted gas (7) relative to the waste gas, the CO2-enriched gas is sent to a unit (CC) for separation by partial condensation and/or distillation which produces a CO2- rich fluid (PL) containing at least 80 mol% of CO2 and at least one portion of the first CO-enriched gas (7) is separated by permeation (M) to form a second CO2-enriched gas (21) relative to the first CO-enriched gas at a first pressure and a gas (15) richer in CO than the at least one portion of the first CO-enriched gas."
