Title:
MOLTEN STEEL MANUFACTURING FACILITY AND MOLTEN STEEL MANUFACTURING METHOD
Document Type and Number:
WIPO Patent Application WO/2019/039666
Kind Code:
A1
Abstract:
A molten steel manufacturing facility according to an embodiment of the present invention comprises: a molten steel manufacturing apparatus having a melting gasification furnace for melting reduced steel to manufacture molten steel; and a gas treatment apparatus for producing a raw material by a synthesis reaction using CO and H2 in the gas exhausted from the molten steel manufacturing apparatus. Therefore, according to embodiments of the present invention, any one high value-added chemical raw material of dimethyl ether, methanol, and ethanol can be produced by recycling surplus gas generated from the molten steel manufacturing apparatus. Therefore, the molten steel manufacturing facility shows greatly improved economic efficiency compared with the prior art and can produced a chemical raw material at a low cost compared with the production of a chemical raw material in the prior art, thereby ensuring cost competitiveness.
