Pure oxygen (O2) at high pressure is sometimes used in chemical processes instead of air to avoid the high cost of pressurizing all the N2 that inevitably comes with use of air as well as additional cost of capital equipment such as heat exchangers, reactors, etc. through which the (generally unnecessary) nitrogen flows. The decision of which to use (pure O2 or air) is based on the tradeoff between the cost of obtaining the pure O2 (via cryogenic distillation or membrane separation) versus the cost of all the unnecessary N2 running through the process. Your process utilizes O2 at -70°C and 10.2 atm absolute. If the mass flow rate of O2 is 8.0 kg/min, determine the volumetric flow rate of the O2 stream using (a) the ideal gas EOS and (b) the SRK EOS.
