Stupid argon column resistance

The resistance for gas to enter the refined argon column is still related to the column pressure, right? It doesn’t matter as long as the tower pressure remains unchanged!

Plate resistance refers to the pressure drop that occurs as rising vapor passes through the sieve holes in the plate and the liquid layer on the plate. The resistance generated by each tray consists of three components: the tray resistance, the surface tension resistance, and the hydrostatic pressure of the liquid column. When the rising gas passes through the sieve holes of the tray, the change in the cross-sectional area of the flow path creates resistance to the flow; this is known as dry tray resistance ； The rising gas must also overcome the resistance caused by the surface tension of the liquid in order to enter and escape from the liquid layer; this resistance is known as surface tension resistance ； The rising vapor also has to overcome the resistance caused by the static pressure of the liquid layer on the tray in order to rise; this resistance is the static pressure of the liquid column. A larger heat source means more steam is generated, the upward airflow velocity is higher, and the resistance increases ； A large cold source indicates an increased amount of liquid flowing downstream; the liquid layer on the packing or trays becomes thicker, which in turn increases the resistance.
