DEAR air separation:What is liquid oxygen self circulation adsorption? What conditions are needed to realize liquid oxygen self circulation adsorption?
The oxygen extraction rate is ψ= two thousand nine hundred and eighty-two × 99.6/(18100 × 20.9)=0.718=71.8%。 Therefore, efforts should be made
  How does the DEAR air separation unit reduce the cold loss caused by the temperature difference at the hot end?

How does the DEAR air separation unit reduce the cold loss caused by the temperature difference at the hot end?
This is mainly due to the large pumping volume at the beginning. At present, the common method is to carry out intermediate extraction when the cold end of the
  What are the types of distillation columns for producing double high products from DEAR air separation?

What are the types of distillation columns for producing double high products from DEAR air separation?
There are two types of distillation columns which can produce both pure oxygen and pure nitrogen at the same time:
1) With auxiliary tower section. It is an aux
  What is the effect of increasing DEAR air separation process air on distillation conditions and what corresponding measures need to be taken?

What is the effect of increasing DEAR air separation process air on distillation conditions and what corresponding measures need to be taken?
When the amount of process air increases, the rising steam in the distillation column will increase and the amount of liquid condensated in the main cooling wil
  What is the effect of insufficient DEAR air separation process air on distillation conditions?
11/08
What is the effect of insufficient DEAR air separation process air on distillation conditions?
When air volume decreases, both the amount of rising steam and the amount of reflux liquid in the tower decrease, but the reflux ratio can still be maintained u
  How are rare gases distributed in DEAR air separation columns?
11/05
How are rare gases distributed in DEAR air separation columns?
Rare gases are argon, neon, helium, krypton and xenon. Since their boiling points are different and their contents in the air vary considerably, the components
  DEAR air separation:What are the basic methods for extracting rare gases?
11/04
DEAR air separation:What are the basic methods for extracting rare gases?
The basic methods for extracting rare gases are mainly based on their different boiling points and molecular differences. However, due to their very small conte
  What effect does the DEAR air separation unit have on the unit when extracting rare gas?
11/03
What effect does the DEAR air separation unit have on the unit when extracting rare gas?
If rare gases are extracted from DEAR air separation units, additional equipment must be added. Most of these devices operate at low temperatures, which necessa
