Product Introduction:
Oxygen is a component of air, colorless, odorless and tasteless. Oxygen has a higher density than air, and its density is 1.429 g/L under standard conditions (0°C and atmospheric pressure 101325 Pa). The method of large-scale oxygen production is to fractionate liquid air. First, the air is compressed, and then it is frozen into liquid air after it expands. Since the boiling points of rare gases and nitrogen are lower than those of oxygen, after fractionation, what remains is liquid oxygen, which can be stored in high-pressure cylinders.
