Tokyo test plant

Experiments on the Tokyo Test Plant were started in December 1977 and ended in August 1979. Using mainly the aforementioned classified refuse, this plant was operated continuously for a long time, in order to reconfirm the requirements for stable operation, utilities requirements and pollution control-related figures established by the Tobata pilot plant as well as to study the feasibility of larger-size plants scale-up.

The daily disposal capacity was 16 to 22 tons for the Tobata pilot plant, and 45 to 50 tons for the Tokyo test plant. 

A conceptual design of an improved technology stack operating at 120 psi (8.2 atm) and 405°F (207°C) was produced based on cell and stack development and tests. The stack was designed for 355 10 ft (approximately 1 m ) cells to produce over 1 MW dc power in the same physical envelope as the 670 kW stack used in the 11 MW PAFC plant built for Tokyo Electric Power. The improvements made to the design were tested in single cells, and in subscale and full size short stacks.

In a study of 63 industrial effluents collected from a wide range of chemical manufacturers from across the United States, carbon disulfide was found in six of the effluents at concentrations less than 10 pg/L and in two of the effluents at 10-100 pg/L (EPA 1979). Analysis of influent and effluent samples from a waste water treatment plant in Tokyo showed carbon disulfide to be the least prevalent among five sulfur-containing odorous compounds for which testing was done (Hwang et al. 1995).
