Urgent! Urgent! The passivation problem of high-pressure diol

The Anchun 1400 tower currently has a high pressure difference, and scaling is a concern. Planning to replace it in the near future. May I ask what the minimum empty speed for passivation of this type of tower is? Can scar formation on the catalyst lead to complete passivation, and will it cause tower damage? The company currently does not have the conditions for passivation; are there any other passivation methods? Like steam? Currently, there are 3 circulation pumps with a capacity of 6 cubic meters per minute; no inerting machine is available, and the nitrogen station can supply up to 6 kilograms of nitrogen. Is it possible to carry out passivation with this setup? Thank you all for your suggestions.
