Abstract

A computer simulation of the chemical process of direct iron reduction in aggregates is performed with the help of the MIDREX technology. Four variants of this technology, which differ by the type of raw material and working process temperature, are analyzed. It is determined that when the process temperature increases, the required consumption of natural gas decreases and the methane in the waste gas is completely removed. It is also noted that at a constant process temperature, the concentrations of all of the components of the system linearly depend on the flow rate of the reducing gas. This circumstance allowed us to record a single balance equation for all of the variants of the studied chemical process.
