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?
