Iron and steel is an energy intensive industry and its contribution to the pollution of
environment is considerable. Direct reduction iron (DRI) is a major element of an iron and steel
production plant. Its share in natural gas and electricity consumption oftotal plant is estimated to
be 70% and 15% respectively. Reduction gases are produced in natural gas reforming unit and its
elements are CO and H2. A major consequence of using this technology is high level of CO2
emission, which pollutes the environment. An alternative to the existing technology is utilization of
H2 as reducing agent. A comparison of various hydrogen production processes indicate that
thermal decomposition of methane provides an attractive option from economical and technical
point of view. Therefore, a system for producing hydrogen, based on thermal decomposition
technique, has been designed in the framework ofthe present paper.
