I have a dry air at 3040 Nm3/h 30 deg C and 5 bars (abs), now we want to make it to 97%N2 by adding dry nitrogen gas at the same gas parameters. We need to decrease the O2 level of the fluidizing unit in order to decrease the chance of copper concentrate sintering after drying it. Now, how much dry nitrogen will we add to achieve 97%N2?
