It can be seen from Fig. 1 that the operating condition of Tokyo Tech process differs from other processes such
as sub-critical water oxidation and waste autoclave. Not only is the aspect of temperature different but also the water
phase usage (it uses the saturated phase). Therefore, the operating pressure is not so high compared with ordinary
water-phase hydrothermal treatment processes.
The commercial scale plant shown in Fig.2 has already been working in Hokkaido, Japan, operated to process
the wastes from nearby medical facilities. The 3m3 reactor is capable of handling up to 1 ton of waste per batch,
generally applying middle pressure steam up to 3MPa while mixing the waste and steam using rotor blades driven
by 30kW electric motor.
