Managing the Energy Cost of On-Site Nitrogen Generators
Energy cost at 0.10/kwh = 182kwx.10x6240 ÷ 1000 = 0.10 / k w h = 182 k w x .10 x 6240 ÷ 1000 = 113.48/cfm/yr. Take that to $114scfm/yr for dry air, this is a very conservative value. Changes in the Electric Energy Rate (kwh) and operating hours will change the value proportionately.
Compressed Air Energy Storage (CAES)
The special thing about compressed air storage is that the air heats up strongly when being compressed from atmospheric pressure to a storage pressure of approx. 1,015 psia (70 bar). Standard multistage air compressors use inter- and after-coolers to reduce discharge temperatures to 300/350°F (149/177°C) and cavern injection air temperature
