How to protect it after the hydrogenation reactor is opened? ? ?
After the hydrogenation reactor is opened, it is advisable to keep nitrogen flowing through the reactor at all times to prevent spontaneous combustion of ferrous sulfide.
Alkali washing is required to prevent polythionic acid stress corrosion cracking
After the reactor is opened, nitrogen is first introduced to prevent ferrous sulfide from catching fire on its own.
After the reactor is opened, nitrogen is first introduced to maintain a slight positive pressure of nitrogen, thereby preventing spontaneous combustion of ferrous sulfide.
Generally, nitrogen protection is used. In terms of equipment: special attention must be paid to protecting the octagonal gaskets and the flange sealing surfaces!
1. Nitrogen protection 2. Cooling to prevent catalyst damage
After the reactor is opened, nitrogen is first introduced to maintain a slight positive pressure of nitrogen, thereby preventing spontaneous combustion of ferrous sulfide. In addition, rainproof measures should be in place to prevent rainwater from entering
Nitrogen protection is essential; it is necessary not only to protect the reactor, but other equipment and pipelines also require corresponding nitrogen protection measures.
Is ferrous sulfide still prone to spontaneous combustion at room temperature?
