DEAR Air Separation's heart and romance

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
