Integrated directly reduced iron production and power generation

摘要

A system for producing directly reduced iron integrated with a turbine power generator (560) and preferably a cryogenic air separation plant wherein off-gas (125) from the direct reduction (510) after drying (520) and compression (530,540) drives the turbine (560) and preferably oxygen (15) from the air separation plant (700) is used to generate synthesis gas for the direct reduction and nitrogen from the air separation plant dampens NOx generation and augments power generation in the turbine.
