Operation of cryogenic air separation equipment

What requirements and regulations should be met for the assembly of meter tube, cold insulation box and strength and air tightness test before positioning of air separation equipment

The volume fraction of carbon dioxide in air is generally around 0.03%, if the air compressor compresses the air to 0.62 MPa, the partial pressure of carbon dioxide can be calculated as 186 Pa. At the temperature when the air enters the air separation device, the saturated vapor pressure of carbon dioxide is much higher than the partial pressure of carbon dioxide, so carbon dioxide is in an unsaturated state, and carbon dioxi...
