Problems with injecting hydrogen into the hydrogenation reactor
Thread Content
Hydrogen is supplied to the inlet of the hydrogenation reactor, controlled by a control valve, with the signal from the analyzer at the outlet of the quench tower feeding back into it. I want to ask if the analyzer is easy to use? How to determine the value of the control valve? Sorry, I’m a newbie. Thank you
Determine the amount of hydrogen to add based on the hydrogen content in the exhaust gas as indicated by your hydrogen analyzer; add more if it’s too little, and less if it’s too much. Your process cards should include indicators for the hydrogen content in the exhaust gases.
The prerequisite for ensuring complete hydrogenation of sulfur dioxide in the reactor is an appropriate hydrogen concentration; close attention should be paid to the analysis data from the on-line hydrogen concentration monitor, with the concentration to be maintained at 1-2 percent.
