1. A method for operating a Rankine cycle power plant of the type having a vaporizer member responsive to heat input for vaporizing a working fluid and producing vaporized working fluid, a turbogenerator responsive to vaporized working fluid for generating power and producing heat depleted working fluid, a condenser member responsive to said heat depleted working fluid for condensing the same and producing condensate, and means for returning said condensate to the vaporizer, said method comprising:

  • a) providing a liquid having a plurality of fractions;

    b) distilling at least one fraction from said liquid to produce a distillated fluid; and

    c) supplying said distillated fluid to said power plant as the working fluid;

    d) operating the power plant with said liquid;

    e) using a member of the power plant for distilling a fraction from said liquid to produce said distillated fluid; and

    f) removing the last mentioned fraction from said power plant, and thereafter operating the same with said distillated fluid.
