INHIBITED ACID CLEANING:-
3. Circulate inhibited Acid (5-6 % Citric Acid and 1% Rodine 213) along with non ionic wetting agent like RXSOL-T300 through Exchanger Loop for 6 to 8 hours
4. It total iron concentration reaches 5000 - 8000 PPM and concentration below 2% acid percentage then dump the cleaning solution and repeat the cycle with fresh inhibited acid.
5. Samples to be tested for pH, TDS and iron on hourly basis.
6. Normal operating temperature should be 50-60º C.
7. When iron concentration and acid concentration of solution reaches steady state and cleaning in completed. Drain the cleaning solution.
NEUTRALIZING:-
8. Circulate 1-2% solution of soda Ash for one to two for neutralization.
9. Rinse the neutralizing solution with water till pH of Inlet and Outlet is same.
PASSIVATION:-
10. Immediately fill and Circulate with 1-3% of solution of sodium Hexametaphosphate for 4-6 hours keeping operating temperature around 50-60º C. Analyze for Phosphate levels in Inlet and Outlet. (Normally maintain 30-40 PPM O-PO4 level)
11. Drain the passive solution without flushing with water.
DRYING:-
12. Dry the circuit with dry air/N2.
