Direct reduced iron (DRI), also called sponge iron, is produced from the direct reduction of iron ore (in the form of lumps, pellets, or fines) to iron by a reducing gas or elemental carbon produced from natural gas or coal. There are different methods for this purpose, including Midrex, HYL, PERED, etc.
Which is better and why?
Which use less energy?
Which one has less capital and operating cost?
#Sponge_Iron #DRI #HYL #MIDREX #PERED #SLRN
Midrex. It consumes less energy, lean gas for metallisation and can definately handle ven low fe bf grade pellets with metallisation upto 93%. The fines losses are also low. As it is widely adopted now a days.. developments and researches in gas based dr process are in areas midrex to the maximum, hence giving scope for process developments and energy efficiency.
