Oxygen and nitrogen have a certain state under certain conditions. When the temperature reaches the boiling point under certain pressure, they will change from a liquid state to a gaseous state. When the pressure is constant, both oxygen and nitrogen have their fixed boiling points. But the boiling point of a mixture of oxygen and nitrogen is neither equal to the boiling point of oxygen at the same pressure nor the boiling point of nitrogen at the same pressure, but between the two. When the temperature reaches the boiling point of nitrogen, the mixture will not boil, and similarly, when the temperature drops to the condensation temperature of oxygen, the mixture will not condense.
DEAR Air Separation enhances the performance of distillation columns and extensively uses structured fillers in their distillation columns. This type of filler can replace saddle mesh filler θ Mesh ring packing can also replace sieve tray towers. It has high mass transfer efficiency and small resistance drop. It is a preferred internal component for distillation columns in ultra-low pressure process air separation equipment. The Tianjin University ZUPAC PLUS structured packing selected for Deer Air Separation can significantly reduce pressure, improve separation efficiency, and reduce liquid holding capacity. The start-up time of the device has also been significantly reduced.
