For towers operating online, where severe scaling occurs on the lower back side of the trays, how can this scaling be removed while the tower is still in operation?

In the quench tower of an MTO unit (methanol to olefins), severe scaling occurs beneath the trays during operation; how can this scaling be removed without shutting down the unit? Those who work at petrochemical plants and have similar experience, please share some advice. Thank you very much
First, it is necessary to determine the composition of the scale, and then take targeted action by using alkaline or acidic water for steaming.
A tower can be connected in parallel; after online switching, cleaning can be carried out.

First, analyze the composition of the scale to determine the cleaning method to be used, and then decide on the specific plan for online cleaning based on the layout of your system Contact is needed
