Abstract: A method of operating an organic rankine cycle system wherein a liquid refrigerant is circulated to an evaporator where heat is introduced to the refrigerant to convert it to vapor. The vapor is then passed through a turbine, with the resulting cooled vapor then passing through a condenser for condensing the vapor to a liquid. The refrigerant is one of CF3CF2C(O)CF(CF3)2, (CF3)2 CFC(O)CF(CF3)2, CF3(CF2)2C(O)CF(CF3)2, CF3(CF2)3C(O)CF(CG3)2, CF3(CF2)5C(O)CF3, CF3CF2C(O)CF2CF2CF3, CF3C(O)CF(CF3)2.

Abstract: A method and system for recovering oil is used in an organic rankine cycle (ORC) system to recover oil from an evaporator of the ORC system and return the oil to an oil sump. The ORC system includes an evaporator, a turbine, a condenser and a pump, and is configured to circulate a refrigerant through the ORC system. The oil recovery system includes a recovery line configured to remove a mixture of oil and refrigerant from the evaporator. The mixture of oil and refrigerant passes through a heat exchanger in order to vaporize liquid refrigerant in the mixture and produce a mixture of oil and vaporized refrigerant. A delivery line is configured to deliver the mixture of oil and vaporized refrigerant to the turbine, at which point the oil may be separated from the vaporized refrigerant and recycled back to the oil sump.

Abstract: 583258 A system for recovering oil in an organic rankine cycle (ORC) system having an evaporator 16, a turbine 18, and a condenser 12, comprises a recovery line configured to remove a mixture of oil and refrigerant from the evaporator 16, a heat exchanger 34 configured to increase a temperature of the mixture such that liquid refrigerant in the mixture is vaporized to produce a mixture of oil and vaporized refrigerant, and a delivery line configured to deliver the mixture of oil and vaporized refrigerant to the turbine 18. The delivery line delivers the mixture of oil and vaporized refrigerant to a discharge housing of the turbine 18, and the discharge housing separates the oil and the vaporized refrigerant.

Abstract: A system for producing power using an organic Rankine cycle (ORC) includes a turbine, a generator, an evaporator, an electric heater, an inverter system and an organic Rankine cycle (ORC) voltage regulator. The turbine is coupled to the generator for producing electric power. The evaporator is upstream of the turbine and the electric heater is upstream of the evaporator. The evaporator provides a vaporized organic fluid to the turbine. The electric heater heats the organic fluid prior to the evaporator. The inverter system is coupled to the generator. The inverter system transfers electric power from the generator to a load. The ORC voltage regulator is coupled to the inverter system and to the electric heater and it diverts excess electrical power from the inverter system to the electric heater.
