Cleaning Shell Side of Exchanger
Cleaning Shell Side of Exchanger
(OP)
Hello Guys,
Quick question to a problem we are having.
Shell and Tube exchanger over time has developed low heat transfer issue. Cooling water is on the shell side. Delta T has decreased from 12C to 2C over the past few months.
Now suspecting the cooling water side of the tubes have lost effectiveness due to fouling maybe from calcium. Initial thinking is we could mix diluted HCl and do an acid soak. The material of construction is carbon steel.
Anyone have an idea on the strength of the HCl and soaking times?
Also any other ideas for cleaning?
Thanks,
K

Is it carbon steel for both tubes and shell?
