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:
An oil-removal system for preventing failures in an Organic Rankine Cycle ORC System 10. The ORC system 10 includes an evaporator, a turbine 18, a condenser 12 and a pump 14, and is configured to circulate a refrigerant 22 through the ORC system 10. The oil-removal system is used to remove oil from certain areas of the turbine 18, and includes an eductor line 32 and an eductor system 20. The eductor line 32 is located upstream of the turbine 18 and is configured to receive a portion of the refrigerant 22b exiting the evaporator 16. The eductor line 32 delivers the refrigerant 22b to the eductor system 20 which is also configured to remove oil from inside the turbine 18.
Abstract:
A vapor expansion system includes a normally closed pneumatic valve between the evaporator and the turbine inlet, with the valve being selectively actuated by the flow of refrigerant vapor from the evaporator so as to enable opening the valve only during periods in which sufficient pressure has built up in the evaporator to properly operate the turbine. A bypass line has a normally open pneumatic valve with an actuator that is similarly caused to operate by pressurized refrigerant vapor from the evaporator. Both actuators are vented to the condenser such that the refrigerant vapor vented from the actuator does not escape to ambient.

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.
