OIL RECOVERY FROM AN EVAPORATOR OF AN ORGANIC RANKINE CYCLE (ORC) SYSTEM WHERE A DELIVERY LINE DELIVERS THE MIXTURE OF OIL AND VAPORIZED REFRIGERANT TO A DISCHARGE HOUSING OF THE TURBINE WHICH SEPERATES THE OIL

摘要

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.
