What should I do if the hydrogen content meter at the quench outlet is broken?

As above, how to control the amount of hydrogen injection?
First, you should describe the process you used? Producing hydrogen from an online furnace? External hydrogen supplementation? The situation of the online furnace can be controlled according to the air distribution ratio of the online furnace and the temperature rise of the hydrogenation reactor. External hydrogen can be controlled in a short time by using the ratio of hydrogen to process gas, combined with the temperature rise of the hydrogenation reactor and the pH value of the quench tower.
The empirical value of hydrogen flow rate, the temperature and temperature rise of the hydrogenation reactor, the pH value of the quenching water, the air distribution of the Claus section, etc. can all be referred to to maintain the production of the hydrogenation section. But I think it's best not to insist, cut out the exhaust gas, and contact the instrument to deal with it. Wouldn’t it be nice to cut back after handling it?

Strengthen the number of analyses, and adjust according to the analysis results. Personally, I think: If "the pH value of the quench tower is controlled for a short time", the PH reaction in the quench tower will be very slow. It should be judged based on the temperature rise of the hydrogenation reactor and the temperature rise of the incinerator. . . . . . . . .
It is mainly judged based on the temperature rise of the hydrogenation reactor and the hydrogen flow rate under normal conditions.
