Research and development of new cokemaking process (SCOPE21) was conducted in Japan from 1994 to 2003 by the Japan Iron and Steel Federation (JISF). Pilot plant scale test of SCOPE21 process was conducted successfully and targets of the project were confirmed. SCOPE21-type new coke oven battery was constructed at Nippon Steel Oita works and the operation of new coke plant started in 2008. The coke production capacity is 1 million ton per year. At present, high quality coke has been produced in this process using high blending ratio (over 50%) of non- or slightly-caking coal.
Method 303 regulations require that each battery be “read” everyday of the year. Allowable emissions are based on the percentage of leaks found per area and the average time of leaking emissions per charge over

Blast furnace coke analysis
♦ How is the coke formed? What happens during coking process? What’s the blast furnace requirements and the role of the coke in the process (Thermal – Chemical – Structural). How is the coke quality determined for Cold Strength and Hot Stability?
The author analyses the coke test facilities for the main parameters and index as MICUM – IRSID – CSR – CRI. The coal and coke test facilty allows to have valuable information regarding the important effect during coking as wall pressure during the distillation process.
♦ Cokemaking emissions represents, perhaps, the greatest environmental concern tne integrated steel industry: to prevent the public from harmful emissions a further reduction of the air pollution is worldwide in the main focus of the authorities and continue to be a target of federal environmental regulations. .
What is coal? A natural dark brown to black graphitelike material, an organic sedimentary rock formed from fossilized plants and consisting of amorphous carbon with various organic and some inorganic compounds: coal is a fossil fuel formed from plants that were buried millions of years ago. The high-temperature, high-pressure conditions transformed the plants physically and chemically, forming coal.
