    Air cooler fouling and cleaning methods

    What would be the best way to do a chemical cleaning of HDS plant reactor effluent air cooler (before the high pressure separator) that is fouled with anorganic salts (bisulphides and chlorides) and maybe some solidified heavy (vacuum) gas oil? Shoud I use water, or water and some chemical agent?
