  • Apparatus for treating flora and fauna waste with hydrothermal reaction
    Patent number: 6464861
    Abstract: An arrangement for treating flora and fauna waste such as garbage under subcritical pressure and temperature. A slurry preparation unit (10) mixes the flora and fauna waste (11) with water (12) and sodium hydroxide (13) to prepare a slurry. A diaphragm pump (16) then pressurizes the slurry to subcritical pressure of water (20 Mpa). Subsequently, a hydrothermal reaction tube (25) heats the pressurized slurry to cause hydrothermal reaction in a subcritical condition thereby obtaining dissolved waste. The dissolved waste is depressurized and fed to an oxidization unit (22) for oxidation.
