<p>Oxygen is separated from air in a cryogenic air separation plant 2, is compressed in compressor 4, and supplied to a plant 6 in which steam and coal react with the oxygen to produce primarily carbon monoxide and hydrogen and the thus formed reducing gases reduces iron oxide to iron. The resulting calorific off-gas is compressed in compressor 20 and is then burned in the combustion chamber 24 of a turbine 22 employed to drive a generator 26 of electricity. The electricity thus generated may be used to meet at least some of power requirements of the air separation plant 2 and the compressors 4 and 20.</p> |
