Once air enters rectification tower inside later, through the action of each working procedure, can be mixed into oxygen by depart eventually nitrogen. What we want to understand is this separate course, this ability is the meaning seat that rectification tower uses, will introduce in detail for everybody below.
The interior of rectification tower is set multilayer tray, and the liquid layer that there is certain ply on tray, after compressing air to wait for material via cleared moisture, carbon dioxide, can be cooled to reach in heat exchanger expand, send into the bottom of next towers eventually. At this moment, the rise of next towers enrages every to come up against lower than its temperature liquid through a tray, make the temperature of itself of body of bring about the desired sensation also meets those who have fixed rate to reduce, partial steam condensation becomes a liquid. As a result of the character of oxygen and nitrogen, they want condensation of more than nitrogen ground to come down in the oxygen in the process of condensation, resemble chasing a condensation so, can form liquid nitrogen. It is when the liquid in indecent process, every are come up against through a tray below the aerification after the steam with nether higher temperature, it is the cause because of character of two kinds of material likewise, evaporate of more than oxygen ground gives out nitrogen come, chroma of the oxygen in the liquid that remain progresses somewhat. Accordingly, the course issues the rectify of the tower, but air preliminary depart becomes sky of oxygen boosting fluid and liquid nitrogen. Want to depart oxygen and nitrogen thoroughly, still need again rectification, and the principle of this part and the principle of rectify issueing a tower are identical, this is the process that oxygen, nitrogen becomes air depart inside rectification tower.
