The hydrogen content in the water vapor stripping tower of the separator behind the medium-pressure reactor is 16%

15,000 cubic meters of dry gas; hydrogen production from natural gas. In the first, second, and third separation tanks following the medium-pressure reactor, as well as in the so-called purification steam stripping tower, hydrogen is present in the vent gases released on site. I would appreciate it if experts could advise me on what causes this phenomenon. Learn together * Improve together
First, check whether the steam in the stripping tower contains hydrogen, identify any devices where hydrogen may be leaking at the points where steam is used, and verify whether the four liquid separation tanks are empty. Introduce medium-pressure gas into the stripping tower. Additionally, check whether the amount of condensate water is high or the liquid level is too high, as this can prevent effective separation of gas and liquid, resulting in the liquid phase containing gas!
Inspect each line that is in contact with or connected to hydrogen one by one to determine the efficiency of vapor-liquid separation in the medium-pressure transformer
Keeping the liquid level at 75% didn’t make any difference
From a process perspective, it definitely goes through the gas-liquid separation tank. If the liquid level is fine, then there is a problem with the vapor-liquid separation; after all, water cannot dissolve large amounts of hydrogen. You can find a wide-mouth glass bottle and place it over the drain of the control valve to check if there is air present; however, be careful to avoid burns.
Is there any one of the several water storage tanks that has a false liquid level? Try adjusting them one by one.
These have all been adjusted; each one was adjusted without any issues
Hydrogen is poorly soluble in water; as long as the separation is thorough and there is a liquid level in the water separator, this situation will not occur. Check to see if stripping steam has mixed into the hydrogen stream
