MULTI-PRESSURE ORGANIC RANKINE CYCLE

摘要

The present disclosure relates to a multi-pressure stage, organic Rankine cycle (“ORC”) that includes a dry organic working fluid that flows through a high pressure stage and a low pressure stage. In one embodiment, a high pressure evaporator and a low pressure evaporator may be arranged in series. In other embodiments, the evaporators may be arranged in parallel.

主权项

1. An organic Rankine cycle comprising:
a dry organic working fluid flowing in both a high pressure stream and a low pressure stream; a high pressure stage through which the high pressure stream flows; a low pressure stage fluidly coupled to the high pressure stage, wherein the low pressure stream flows through the low pressure stage; a mixer configured to combine the high pressure stream and the low pressure stream, wherein a mixed enthalpy stream exits the mixer; a condenser configured to condense the mixed enthalpy stream; and a tee configured to split the mixed enthalpy stream exiting the condenser into the high pressure stream and the low pressure stream.
