Abstract (en)
[origin: FR2866900A1] Process for renovation of a vertical furnace supplied with an oxidising fluid partially supplied by a gas separation from air(ASU) ; more than 50% of the flow from the blower supplying the furnace is injected in a cryogenic separation unit to produce oxygen of purity greater than 90%.The air flow from the blower and/or air pressure are controlled by a regulator which measures the flow rate or pressure of the air at the entry and/or exit of the air purifier upstream of the ASU.The supply fluid to the furnace is pure oxygen or oxygen diluted with air from the cryogenic unit.
