Where is argon distributed in the DEAR air separation distillation column and what factors influence its distribution?
The volume fraction of argon in air is 0.932% and its boiling point is between oxygen and nitrogen. As it enters the lower column and rises one by one along the
  DEAR air separation:Why can not the argon fraction tap be located where the hydrogen content is the highest?

DEAR air separation:Why can not the argon fraction tap be located where the hydrogen content is the highest?
It can be seen from the distribution diagram of argon in the upper tower that there are two argon rich areas in the upper tower: one in the distillation section
  How to configure the crude argon column when the DEAR air separation unit extracts crude argon?

How to configure the crude argon column when the DEAR air separation unit extracts crude argon?
The argon fraction extracted from the main column in the crude argon column is separated preliminarily to obtain argon 95%-98%, oxygen 1%-3% and nitrogen remain
  How much argon fraction can be extracted from the DEAR air separation column when producing argon? What are the limitations?
10/25
How much argon fraction can be extracted from the DEAR air separation column when producing argon? What are the limitations?
The argon fraction is separated from oxygen and argon in a crude argon column. The argon fraction enters from below, and at the top it yields roughly 95% argon.
  What effect does the DEAR air separation column have on the operation of the main column when producing argon?

What effect does the DEAR air separation column have on the operation of the main column when producing argon?
The main tower of the DEAR air separation tower and the crude argon tower are organically connected through the argon fraction outlet position, the liquid-air f
  What is the requirement for the main tower when configuring the argon column in the DEAR air separation column?
10/21
What is the requirement for the main tower when configuring the argon column in the DEAR air separation column?
Argon distribution in the main column of DEAR air separation column varies with the position of the liquid air inlet. With the increase of liquid air inlet posi
  Why do DEAR air separation plants with argon columns require particularly stable operating conditions and how can they be adjusted when the argon distillation distribution changes?

Why do DEAR air separation plants with argon columns require particularly stable operating conditions and how can they be adjusted when the argon distillation distribution changes?
The distribution of argon in the upper column is not constant. When the purity of oxygen and nitrogen changes, i.e. the operating conditions change slightly, an
  How does DEAR air separation remove oxygen from crude argon?
10/15
How does DEAR air separation remove oxygen from crude argon?
The crude argon produced by distilling the argon distillate in the crude argon column contains 95%-98% argon, 1%-3% oxygen and 3%-5% nitrogen. In order to produ
