The function of instrument air in the tower bottom section
Thread Content
In the acrylic acid production process, instrument air is introduced at the bottom of the purification tower; it is said that this helps to prevent polymerization. What is the exact principle behind this?
Instrument air is essentially clean compressed air, which is used to disperse particles and increase their diffusion, thereby preventing molecules from sticking together
Hm? Will it have an impact on the pressure inside the tower? Why not use an inert gas such as nitrogen?
Oxygen in the air can act as an antipolymerization agent.
