METHOD FOR PRODUCING SYNGAS IN COMBINED OPERATION WITH A METALLURGICAL PLANT

摘要

The invention relates to a method for generating synthesis gas in conjunction with a smelting works (1), which comprises at least one smelting furnace (2) for generating pig iron, a converter steel plant (3), and a coke furnace plant (4). A part of the smelting furnace gas (6) produced by the pig iron generation and/or a part of the converter gas (7) occurring in the converter steel plant (3) and/or a part of the coke furnace gas (8) occurring in the coke furnace plant (4) are mixed. By selection of the gas streams combined into a mixed gas and/or by modifying the mixing ratios of the combined gas streams, at least two utility gas streams (13, 14) are produced, which differ in respect of the composition thereof and are both processed into synthesis gas streams.
