Abstract
A system for energy optimization in a plant () for producing direct-reduced metal ores (). The plant () has at least one reduction unit (), a device for separating gas mixtures () having an associated compressing device (), and a gas-heating device () upstream of the reduction unit (). Part of the process gases () is fed by a feed line from a smelting reduction plant to the plant for producing direct-reduced metal ores (). A turbine () is fit between the device for separating gas mixtures () and the gas-heating device () upstream of the reduction unit () such that a pressure drop between the device for separating gas mixtures () and the reduction unit () is converted into forms of energy that can be used to operate additional components () of the plant (), in particular electrical energy and/or mechanical energy. Energy consumption of the plant () is reduced.
