Question:

A schematic of a variation on the Rankine cycle is shown in Figure P5-9—not for steam but for an organic fluid. This process has been called the “organic Rankine cycle”:

A. Do some research and determine the major advantage of using a Rankine cycle with an organic as a working fluid as opposed to water.

B. There are five unit operations in the process in Figure P5-9. Describe what is happening in each of those steps (for the organic working fluid).

C. There is a valve between line 4 ➝ 5. Why do you think that line exists and why do you think that valve is there? THERMAL OIL Boiler FIGURE P5-9 3 2 Pump 8 6 5 Generator Regenerator WATER Condenser
