How to determine the presence of non-condensable gas at the top of a tower (the top of some condensers and containers)

The main factor is pressure; under the same temperature conditions, the higher the amount of non-condensable gas, the higher the pressure. ——The so-called non-condensable gas is only meaningful in the context of equipment where there is no continuous gas emission; when the pressure rises, gas is discharged intermittently to reduce the pressure. ——In the case of continuous gas emissions, it should be non-condensable gas at specific temperatures and pressures.
”It’s mainly pressure; under the same temperature conditions, the higher the amount of non-condensable gas, the higher the pressure. Are there any other values that can be used to determine this besides pressure?
I don’t know, that’s why I’m asking
If there is non-condensable gas at the top of the tower, the dry points of the top product and the side-stream products will decrease, and the temperature at the top of the tower will also drop. Therefore, it is necessary to control the overhead pressure properly, and it is essential to discharge the non-condensable gas on a regular basis.
