How to judge the main condenser evaporator leakage?

Answer: when the main cooling is seriously leaked, nitrogen with higher pressure will leak into the low pressure oxygen side in large quantities, then

Why doesn't the full low pressure oxygen generator enter air when it starts?

At the beginning of starting the full low pressure oxygen generator, all the air entering the equipment is inflated through the expander, while the to

When the full low pressure oxygen generator begins to accumulate liquid oxygen, is it necessary to keep the liquid level? Why?

The start-up phase of the whole low-pressure oxygen generator is that liquid empty appears first in the lower tower, and then liquid oxygen appears in

What's the disadvantage of liquid appearing too early in the liquid purifier, and how to prevent it?

Liquid appears too early in the liquid purifier, which means that the liquid purifier is connected too early. If the temperature condition of the swit

Why can small air separation plant lower the forward air temperature of the expansion machine instead reduce the high pressure?

Reducing the high pressure of small air separation equipment with medium pressure expansion machine can reduce the energy consumption of air separatio

Mar 18, 2013

What conditions limit the inflated air volume entering the tower?

The expansion air volume entering the upper tower increases, and the reflux ratio of the distillation section decreases correspondingly. In order to a

Mar 15, 2013

Why did small oxygen generator extract part of the distillation gas when producing high purity nitrogen?

The air contains 0.932% argon. When 99.6% oxygen is to be produced from the upper tower, 1.05% argon must be contained in the nitrogen discharge. From

Mar 15, 2013

Why does liquid nitrogen throttle have the most sensitive position to adjust liquid nitrogen purity?

When the small oxygen generator uses liquid nitrogen throttle to adjust the purity of liquid nitrogen, it can be found that the valve is adjusted with

Mar 15, 2013

When the liquid passing capacity of the liquid-air regulating valve is not enough, what influence will it bring to the rectification working condition?

If the passing capacity of the liquid-air regulating valve selected in the design is too small, or it is replaced with the liquid nitrogen regulating

Mar 15, 2013

What are the saturation temperature, saturation pressure, and what is the relationship between them and boiling point, evaporation temperature, condensation temperature and so on?

Saturation temperature and saturation pressure are terms in gas-liquid equilibrium. If it is not filled with liquid in a sealed container, part of liq
