Segway from the other conversation. Is there anything that gets me back to a C-factor of 120 for a dry system if I use nitrogen instead of air? What happens if I don't maintain the nitrogen part of the generator? Does air get pumped in or does it stop pumping altogether and I deal with the low air alarm eventually? Ballpark what is upcharge for nitrogen vs. air? I've heard mid $teens. If so makes me wonder who's really willing to pay. Just a few I suppose. As EOR I don't want to be throwing around $$$ just because it's a good idea. For example, when the generator costs more than the building may want to stick with a regular compressor in an exaggerated case.
