Why are some students so lazy? All you have to do is use the monster search machine, Google, and you will find that you can go to:
http://www.eere.ener...owerplants.htmland there you will find the two basic systems used at the U.S. geothermal sites in Northern California. Sure, the schematic is a "Mickey Mouse" diagram - but so is the thermodynamic process to extract electrical energy from a natural, underground steam source - relatively speaking. This is really basic thermodynamics -- but very important to thoroughly dominate and understand on the part of a Chem E student.
The basics are just that: very, very thermodynamic basics. Keep rocks, boulders, sand, debris and other undesirables out of the steam turbines. Isentropically expand through the turbines down to condensing level or keep a back pressure and condense outside the turbine. You may have to pump (re-inject) the produced condensate back to the magma layer to effect a total power recycle.
You even get a detailed tabular inventory of what turbines and other equipment are being used and their rated MW capacity. What else do you need? If you are a thermodynamic student at the present time, you have gotten more information than any other thermo student got a generation ago. I am not reprimanding you; I'm stressing the point that the information is so available and it is there for your immediate use and exploitation. I hope you use 100% of it and that it helps explain and educate you in the fine style of thermodynamics science.
