Patent ID: 8088273

Claim:
An equipment for upgrading oil to produce a lighter refined oil from a heavier material oil, comprising: an emulsion making portion configured to make an emulsion by emulsifying ionized alkaline water having oxidation-reduction potential of −850 mV or below and a pH of 12 or higher in the material oil; a refinery tank portion configured to store a heat medium and to introduce droplets of the emulsion therein so that the droplets of the emulsion drop onto a surface of the heat medium; and a heating portion configured to heat the refinery tank portion, wherein: an interior of the refinery tank portion is formed in a shape of a closed loop for allowing the heat medium to circulate up and down; and the heating portion includes a heating gas channel portion for a hot gas to flow therein, which includes a lower heating portion configured to heat the heat medium in a closed loop lower portion of the refinery tank portion and a side heating portion configured to heat the heat medium that is heated by the lower heating portion and thereby coming up in a closed loop side portion of the refinery tank portion.
