During reformation, coked regenerated gas is used, with a hydrogen content of around 3% each time

Apart from the poor control of the pressure difference that allows hydrogen to mix in, are there any other reasons? Even if hydrogen gets mixed in, isn’t it burned in the regenerator? How can it still exist?
Carefully investigate the reasons at each stage: sampling, sample transfer, sample analysis, and data calculation. With your question like this, and without any other information to refer to, it’s impossible to determine the reason.
Each of our classes uses burnt gas as a component; it contains a certain amount of hydrogen, and that’s fine – it can still be burned. Is the hydrogen brought about by a catalyst?
What should the flow rate of the replacement gas be? Is it too low? The temperature of the replacement gas could also be increased a bit
What is the principle behind raising the temperature? In my case, nitrogen is added after water cooling, and then it enters the compressor buffer tank
Increase the temperature and flow rate of the displacement gas to better purge the oil and gas
It is recommended to look for the causes in aspects such as sampling, sample bags, analysis process, and accuracy.
