Description
Summary:Computer apodeling and economic analysis have shown that "oxygen" blast-furnace smelting (oxygen content of the blast 55-60% oxygen is both parcticable and highly cost-effective with a natural-gas consumption that makes it possible to obtain top gas suitable for producing ammonia. Here, the cost of the pig iron is reduced by more than 30%, while the wholesale price of the top gas increases in proportion to its calorific value. The use of top gas in place of natural gas for ammonia production also significantly reduces ammonia production costs when the wholesale price of the top gas is 5.5-7 times less than the price of natural gas. Cooperation between blast-furnace shops and nitrogen-fertilizer producers to make use of top gas as the raw material for ammonia production will also lead to a substantial reduction in atmospheric emissions of CO^sub 2^.[PUBLICATION ABSTRACT]
