In the present work SL/RN process based plant is selected for energy conservation as it is oldest and most widely applied process Many investigators considered sponge iron manufacturing process and suggested improvement in that [8 10 11] Directly reduced iron DRI or called sponge iron has been found an excellent feed in electric arc
THE BASICS DRI & HBI DRI can be produced in three different forms Cold DRI CDRI ; produced by cooling the DRI from the DR reactor reduction section and discharged at about 50°C Classified as DRI B by the International Maritime Organization IMO Hot DRI HDRI ; directly discharged from a hot DRI reactor and transported to adjacent captive EAF
The so called Stelco Lurgi/Republic Steel National Lead SL/RN process is a widely used coal based DRI making process which uses a rotary kiln The process uses lump ore pellets beach sand or ilmenite ore and solid carbon to produce hot or cold DRI The process operates at high temperature and atmospheric pressure
Direct reduced iron DRI process In addition to the process route via the blast furnace process there is another option for extracting crude steel from iron ores using the so called direct reduced iron DRI process secondary route The starting point for the efforts to find an alternative to the blast furnace process was the relatively
4 Our proprietary process technology Lurgi MegaMethanol converts natural gas into methanol and offers the highest efficiency available Suited to large scale production Lurgi MegaMethanol converts syngas into raw methanol using a two step reactor process It is a reliable technology that features very low production costs at maximum

The process of hydrogen production at the HGU plant is based on catalytic steam hydrocarbon reforming process which takes place in the Lurgi Steam Reformer at temperatures of over 850°C and the separation of hydrogen from the syngas produced by the PSA Pressure Swing Adsorption technology
Lurgi MTP process The Lurgi MTP process uses a fixed bed ZSM 5 catalyst manufactured by Süd Chemie AG It provides high propylene selectivity in the range of 65 7 % Due to large pore size of the ZSM 5 structure significant amount in the range of 20 30% gasoline range hydrocarbons are also produced Ethylene yield is only in 5 10% range
Underground Coal Gasification UCG is an energy manufacturing process whereby coal is gasified or chemically converted into a gas in situ UCG has several benefits in terms of low capital cost
sponge iron manufacturing process arose in late 50 s when Electric Arc Furnaces EAFs engaged in manufacturing steel started facing problems of availability of scrap of desired quality the traditional source of their iron metallics The DRI processes soon became popular and since the inception of first DRI plant in 1957 in Mexico there has
