Hi everyone,
For ambient air vaporizers (e.g. like the ones that make gaseous nitrogen from liquid nitrogen), my understanding is that the area is selected via empirical correlations and the resulting excess surface area tends to let the resulting gas approach the ambient air temperature. Does this mean that the gas is technically superheated past the saturation temperature?
I think the system is operating at the saturation point of the liquid, which is ultimately controlled by the supply tank’s pressure control scheme (e.g. tank PSV), where the liquid is boiling inside the vaporizer and then the excess heat transfer area is allowing the gas to absorb more energy and deviate from the saturation point. Have I misunderstood how the system functions?
