PUROX system demonstration test on simulated Japanese refuse

Using the PUROX System pilot plant of Union Carbide located at Tonawanda, New York, USA, a demonstration test was conducted on simulated Japanese refuse from June through August, 1978, after making some modifications of the plant. The purpose of the demonstration was to achieve the following three objectives: (1) conduct tests on simulated Japanese refuse and thereby collect additional data to supplement those obtained on US refuse, in order to obtain the technical approval of the Ministry of Health and Welfare (MHW) of Japan for the PUROX System; (2) analyze in accordance with procedures provided in the Japanese Industrial Standard or those established by the Environment Agency and MHW of Japan, in order to evaluate outgoing streams on the basis of Japanese national environmental standards and emission and effluent standards; and (3) obtain engineering data necessary for the design of the components of the Dry Process, namely, the gas combustor, waste heat boiler, and electrostatic precipitator. The results of the pilot tests are presented. The economics of the PUROX system are also discussed.
