A serious problem is predicted to occur to the domestic cokemaking industry in the early years of the 21st century. With the majority of existing coke ovens worn out or obsolete, a significant shortage of coke production would take place. Presently, considering the environmental pollution and improving the work conditions, the development of an innovative process is strongly required for future.
The cokemaking industries in Japan have two candidates as the potential process for the future, i.e., the previously developed Formed coke process and the new Conventional cokemaking process. The project for the latter process has been promoted to develop the innovative process by member companies in The Japan Iron and Steel Federation during eight years since 1994. This project is named after SCOPE 21 (The Super Coke Oven for Productivity and Environment enhancement toward the 21st century). A bench scale test will follow in three years since 1996 and the project is expected to proceed to the 100t/d pilot plant test in next three years until the year 2001.
This process should develop at least the following technical items to realize more economical and clean coke plants.
1) Pre-coking treatment for higher utilization of poor coking coals
2) Coking system for higher productibity
3) Perfect prevention of environmental pollution
In addition, some basic researches are pointed out for the process development toward the 21st century.
