Stable operation of a smelter reactor

Abstract From the Canadian patent

A process of producing molten iron involves: a) introducing iron oxide flux, oxygen, nitrogen, carbon, and hydrogen to a smelter reactor; b) maintaining conditions to cause (i) the iron oxide to be reduced (ii) molten iron to be , created and stirred in the bottom of the reactor surmounted by a layer of , foaming, FeO-containing slag and (iii) carbon monoxide gas to rise through the slag; c) causing at least some of the carbon monoxide to react with the oxygen; d) releasing an offgas containing CO CO2, H2 and H2O; and e) removing , at least some of the molten iron and slag from the reactor. Good process stability is achieved by: f) repeatedly measuring during the process, the , …
