Purification Technology Q&A [012]
Thread Content
Why is it necessary to relieve pressure and fill the vessel with nitrogen after shutting down a low-temperature converter? Answer: 1. To prevent water vapor from condensing and damaging the catalyst. 2. Prevent a negative pressure from forming inside the furnace, as this can allow air to enter and damage the catalysts and equipment.
Prevent water vapor in the process gas from condensing, thereby avoiding damage to the catalyst
1. Prevent water vapor from condensing and damaging the catalyst; 2. Prevent air from entering and damaging the catalyst as well as the equipment.
