Present status of CWM demonstration tests in Japan
- Center for Coal Utilization (Japan)
After oil crisis, R&D crises, R&D of coal fluid technology in Japan was launched by COM (Coal Oil Mixture) technology, R&D of COM technology was completed in 1984 and the technology was commercially applied in Yokosuka project by Japan COM and Tokyo Electric Power Company. On other other hand, R&D of CWM (Coal Water Mixture) technology for higher economic performance and easier equipment maintenance and handling was launched in 1983. After finishing basic researches and pilot plant tests, various demonstration tests such as Nakosa demonstration plant project, Himeji project, Wakayam project, Tomakomai project and Ube project has been conducted while accumulating various information data as shown. In fact, CWM technologies for production, storage, transportation and combustion are satisfactorily in high level for practical applications. However, users especially in general industries are less interested in shifting fuels to CWM at present because of the fall of oil prices since 1986, recent recession in economy and uncertainty about new fuel. Under this circumstances, a new test for CWM distribution relay system, or West Japan Project was launched in 1991 to appeal CWM to users as a more attractive commodity. Emphasis of this demonstration test is placed on a distribution relay system of CWM in which CWM is produced in China and transported to Japan. The manufacture of CWM is a project achieved through cooperation between China and Japan. And this project is a world-first international CWM trade. In this project, it is intended to supply CWM to users more economically and stably through a relay station in Japan. TAYCA Corporation, one of the major Japanese titanium oxide producers is the first user with using 40,000 tons per year in general industries.
