Heat Exchanger Scaling problem

well, I am a new member of your forum and working at an offshore oil platform . Here we are using shell and tube heat exchangers for heating the well fluid. Recently we are facing scaling problem in one of them.
So can somebody demonstrate the procedure to clean the same.

Dear Abhi,

It all depends what is the level of your scaling problem. If it has just started you can flush the exchangers with degreaser, pickling fluid phospahting and passivate the same and put the exchanger on line.

In case its too aggravated then you will have to deploy high pressure water jet cleaning usually you have these machine on the rigs.

Maybe, if your fluids are viscous and your thermal resistance is located in the tubes, you could check the option of wire matrix inserts. They could enhance the coefficients of HT plus due to the distrurbance effect on the boundary layer (responsible for coking, scaling, ...) your fluids would not have the chance to stay for long on the circumference and therefore minimize the rate of chemical reactions thus elongating the time required for maintenance.
(It is an idea, but more for your process is required for detailed analysis).
