Is it gaseous or liquid?

The critical temperature of nitrogen is -147.05 degrees Celsius, and its critical pressure is 3.4 Mpa. Personally, I think this state should be liquid. In typical air separation units, the pressure at the bottom column is around 0.42 Mpa, and the temperature of liquid nitrogen is about -170 degrees Celsius, or even lower!

The saturated vapor pressure of liquid ~~nitrogen at -169 degrees is ~~1.05 Mpa~~
