Is it normal for the hydrogen content in the overhead gas of the reformer’s stabilizer to be around 20%~30%? What are the reasons for the high hydrogen content in the tower top gas? Please give some advice! ! !

It’s abnormal; will there be problems if it comes into contact again?

Are the high-value levels of liquid level, pressure, and temperature after cooling normal? Too low a temperature is also not acceptable; hydrogen evolution is poor, and it ends up in the stabilizer along with the liquid.

The high-phase liquid level is controlled at 30–35%; the operating pressure for the high-phase stage is 1.15 Mpa, with a design value of 1.2 Mpa. The temperature of the product after cooling is around 28–35 degrees! The liquid level in the recontact tank is 35%, and the recontact pressure is 2.4 Mpa! Since the hydrogen produced is sent directly to the hydrogenation unit via a hydrogen production compressor through the recontact process, fluctuations in the pressure of the hydrogenation unit have a direct impact on the recontact pressure! Moreover, the vibration at the pipeline where the reformed product oil mixes with hydrogen is severe; could this be largely related to fluctuations in the recapture pressure? The inlet opening of the hydrogen production compressor is around 3 threads, with the compressor load at 50%! What is the hydrogen content in the normal stable tower top gas?

What is the inlet temperature of the second recontact tank? It seems to be a reforming process with a low processing capacity; the booster uses a reciprocating machine. To be honest, the hydrogen content in LZ’s system is **higher than that in my previous systems**

The inlet temperature of the recontact tank is around 25~30! The restructured design capacity is 250,000 tons/year; the booster is a reciprocating machine! What are the methods to reduce hydrogen content?

It is recommended to send the vent gas from the stabilizer overhead reflux drum to the recontact tank, while increasing the recontact pressure and temperature

It’s useless; what are the advantages of using ammonia for freezing? Is your device in use?
