This design is used with a recycle pump, for hazardous relief products to recover liquids to the...
Internal corrosion could plug some portions of the radiator with debris. It will change the flow pattern and the heat transfer.
We had similar radiation troubles in a mobile power plant we faced, so we replaced the radiator.

Organic chlorinated components from wastewater are stripped with steam with an atmospheric stripper. Is it your case ???. At so low content of contaminants, we usually design a tray stripper, but if you already as a packing column, operational conditions should be designed to have a recycle...
Could you share a photo of the damages ?????. Mechanical damages to only one draw-off could be done in the last maintenance work.

VCM is a trick fluid. VCM pumps are linked with cold VCM storage tanks working at -5°C; it must have a small equalizing line to cool down up to the operating temperature. Other licenses use propylene as a coolant coming from the cooling system of the VCM tank.

Chlorine and fluorine tank will never be open to the atmosphere-- Chlorine is storage in Chloroalkyl plants.in horizontals tanks, Transport is done in special tanks.
Check the chlorine institute web for the USA rules.
