The realizes a variety of objects depart with rectification can effective tower, and as a result of craft mature, equipment is optimized, restricted basically to corporeal function without what. Also be to say, the bag contains the air of a variety of gas, also can achieve detached goal through rectification tower. Particular procedure still needs farther specification.
A variety of gas are contained in air, if common method is affirmative cannot its each composition undertake depart, but if use rectification technology,differred. Carry out a proof, air of microtherm law depart is this adoption principle. Before had not popularized rectification technology, it is to connect membrane separation law or law of pressure swing adsorption to depart normally airy, but the product purity that discovery gets eventually is not ideal. And the boiling point difference that uses oxygen nitrogen implements oxygen nitrogen to depart microtherm law, below environment of high-pressured low temperature, air liquefaction, pass its through rectification in rectification tower after conducting heat character, the oxygen nitrogen composition in air of can effective separate liquid state. This kind of means departs not only efficiency is tall, the purity of earning gas also can reach higher level.
