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.
