Note the following points: 1. Close the regeneration slide valve and adjust the pressure difference between the two vessels so that the reaction pressure is higher than the regeneration pressure, with the pressure difference being greater than 0.01 MPa； 2. The rotation speed of the regenerator should not be too high, to prevent the regenerator from burning out due to insufficient load ； 3. Maintain a high regeneration temperature and control the desulfurization speed appropriately; the temperature of the discharge line must not exceed 450°C as specified, and it is no problem to keep it within 500°C in practice ；
Additional note for floor 2: The leakage should be accelerated at this stage, as the material seal is no longer present.
