Abstract

An apparatus 124 using an aqueous solution consisting essentially of water for forming a compound which retards the deposition of iron-based compounds is disclosed. The apparatus includes a chamber 138 for forming steam which is injected through a nozzle 148 into a chamber 136. The pH of the aqueous solution, which is acidic, is raised in the presence of oxygen to cause Fe++ to come out of solution as a precipitate and the oxygen level is lowered to limit the growth in size of the precipitate.
