Suspension Hydrogen Reduction of Iron Oxide Concentrates


Book Description

The objective of the project is to develop a new ironmaking technology based on hydrogen and fine iron oxide concentrates in a suspension reduction process. The ultimate objective of the new technology is to replace the blast furnace and to drastically reduce CO2 emissions in the steel industry. The goals of this phase of development are; the performance of detailed material and energy balances, thermochemical and equilibrium calculations for sulfur and phosphorus impurities, the determination of the complete kinetics of hydrogen reduction and bench-scale testing of the suspension reduction process using a large laboratory flash reactor.







Flash Ironmaking


Book Description

This book addresses the two major issues faced by the modern steel industry: CO2 emissions and energy consumption. The steel industry accounts for 6.7% of the anthropogenic CO2 emissions and consumes 6% of the total energy consumed in manufacturing. In response to these critical issues, a new technology called flash ironmaking has been developed, aimed at producing iron directly from iron ore concentrate using gaseous reductants/fuels such as natural gas or hydrogen. This ironmaking technology takes advantage of the rapid reaction rate of fine particles and bypasses the palletization process. This book discusses the principles of flash ironmaking, laboratory experiments, and design and operation of a prototype flash reactor. Provides theories and principles of ironmaking and a novel ironmaking technology Includes laboratory experiments to establish the kinetic feasibility of flash ironmaking Covers the design and operation of a prototype flash reactor as well as the design of industrial-size flash ironmaking reactors Describes various cases of flow sheet development, which forms the basis for process analysis and simulation Presents economic analysis case studies Presenting a novel technology that addresses contemporary issues facing one of the largest manufacturing industries, this book is aimed at professionals and researchers in metallurgy, materials engineering, manufacturing engineering, and related disciplines.

2nd International Symposium on High-Temperature Metallurgical Processing


Book Description

High Temperature Metallurgical Processing contains the proceedings of the Second International Symposium on Thermal Processing of Minerals, Metals and Materials. This symposium explores physical and chemical transformations in materials that have been designed to facilitate the recovery of valuable metals or produce other useful materials. Representatives from both industry and academia focused on the latest innovative high temperature technologies. Because high temperature processes require high energy input, the presenters addressed the need for sustainable technologies that could provide low energy consumption and low pollution emissions. The symposium also examined the thermodynamics and kinetics of chemical reactions, phase transformations at elevated temperatures, and characterization of materials used or produced in high temperature processing.
