  • Patent number: 5007240
    Abstract: A hybrid Rankine cycle system comprises a boiler in which water steam is generated, a steam turbine which is worked by the water steam from the boiler to drive a generator to obtain an electric power, an absorber condenser for introducing thereinto strong absorbent solution to absorb the water steam from the steam turbine to produce weak absorbent solution, and a pump for delivering the weak absorbent solution from the absorber condenser to the boiler. The weak absorbent solution is heated in the boiler to produce the strong absorbent solution to be fed to the absorber condenser and the water steam to be fed to the steam turbine.

  • Patent number: 4152218
    Abstract: Apparatus for the distillation of sea water and desulfurization has a vessel directly contacting waste gases exhausting from a boiler with sea water for absorbing sulfur oxides contained within the waste gases, an oxidation device to convert the sulfites that are produced by absorption of the sulfur oxide into sulfates through a catalytic action of metallic ions in the sea water, a decarbonization device, a deaerator, and a heating type distillation apparatus that uses the sea water used for the desulfurization as supplementary water. The oxidation, desulfurization and the separation of air are processes conducted continuously.
