We have a big fouling problem on one of our acid gas strippers. It works on an ammonium carbonate system to remove CO2 and H2S. The make-up water for the tower however has a high silica content and now we sit with a cemented stack of rings which we cannot unpack. The stuff is high in Si, Fe, NH4+, Ca and Al. Are there any detergents or solvents that can at the very least loosen the "cement" from the pall rings so that we can start unpacking and cleaning the stuff properly?

Any help will be appreciated,

John Calvin
