During the passivation process of the hydrogenation reactor, the operation of the quench tower should be () A. stopped B. carried out normally C. increased with more demineralized water being supplied D. the temperature of the quench water increased
Choose C. Hydrogen sulfide is generated during passivation; to keep the quench tower in an alkaline environment, the amount of desalinated water should be increased as much as possible. And monitor the PH of the quench tower at all times.
During passivation of the hydrogenation reactor, quench tower operation (A. Shutdown)
C. Increase the amount of demineralized water added; hydrogen sulfide is generated during passivation
Increase the amount of water used for deoxygenation, reduce the SO2 concentration, and stabilize the pH of the quench water to prevent equipment corrosion
During passivation of the hydrogenation reactor, quench tower operation (C)
B. Normal operation--------------------------
During the passivation process of the hydrogenation reactor, what should the quench tower do? (C) A. Shut down B. Operate normally C. Increase the amount of demineralized water supplied D. Raise the temperature of the quench water
