In some embodiments, operating variables such as bleed extraction pressure and bleed flow rate are selected such that a double pinch is obtained in a feedwater heater, thereby improving the efficiency of the Rankine cycle. In particular, a first pinch point is obtained at the onset of condensation of the bleed and a second pinch point is obtained at the exit of the bleed from the feedwater heater. The minimal approach temperature at the first pinch point can be approximately equal to the minimal approach temperature at the second pinch point. Systems that employ regenerative Rankine cycles, methods of operating such systems, and methods of optimizing the operation of such systems are disclosed herein in connection with the double pinch criterion. | ||||||

| A device for automatically detecting and removing air from a gas mixture of an organic gas and air includes calculating a saturation pressure value based on a temperature of the gas mixture in a reservoir 1, and obtaining a pressure threshold value by adding a margin value to the saturation pressure value. When the pressure value inside the reservoir 1 is higher than the pressure threshold value, air is detected to be in the gas mixture. After this detection, a controller 5 pressurizes and introduces the gas mixture into a pressure container 2 to condense the organic gas in the gas mixture, thus producing a diluted gas mixture. Subsequently, the diluted gas mixture is introduced to a supply side of a membrane unit 3, the organic gas in the diluted gas mixture is recovered at a permeation side thereof, and a residual gas is discharged outside of the device. | ||||||
