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

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

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

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

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

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

What factors are related to the load regulation range of low-voltage air separation plant

The load adjustment range of low pressure air separation plant is related to the adjustment performance of raw material air compressor, the adjustment

Mar 14, 2013

How to increase the output of oxygen?

Besides reducing air loss as much as possible, reducing equipment resistance to increase air volume and reducing loss of running cooling, incomplete l

What problems should be paid attention to when starting centrifugal compressor?

Before starting, the following preparations should be made:1) Check whether the unit has the starting condition (including the reason of last stop and

Mar 12, 2013

What factors can affect the cooling effect of the intermediate cooler of the compressor, and what influence does the poor Intermediate cooling have on the performance of the compressor?

Air compressor intermediate cooler is generally shell-tube structure. Water is supplied inside the pipe, and gas is supplied between the pipes, which
