METHOD FOR TREATMENT OF WASTE GAS CONTAINING CARBON DIOXIDE COMING FROM THE PROCESS OF ELECTROSMELTING

摘要

FIELD: metallurgy.SUBSTANCE: invention relates to metallurgy and can be used at treatment of waste gas containing carbon dioxide coming from the process of electrosmelting. Method involves exhaust gas afterburning using combustible gas, addition of hydrocarbon-containing gas to exhaust gas and conversion of carbon dioxide of exhaust gas at least partially into carbon monoxide and hydrogen, exhaust gas cooling in heat exchange process and use of carbon monoxide and hydrogen mixture for thermal needs.EFFECT: invention improves recovery of exhaust gas formed during electric arc furnace operation and simultaneously reducing emissions of carbon dioxide formed during melting.10 cl, 3 dwg
