<p>Disclosed is a process provided for increasing the fuel value of off-gas (20) recovered from oxygen blowing steel converters (10, 100). Carbon is introduced into an off-gas capture hood (22) to react with carbon dioxide therein to form carbon monoxide. A carbon dioxide curtain (61) is formed which surrounds the inlet end of the gas capture device (22) to prevent air from entering the capture device. Carbon dioxide is drawn from the carbon dioxide curtain (61) into the capture device (22) to mix with the gases therein.</p> |
