WebSep 1, 2024 · However, control of the phosphate concentration is difficult due to the compound’s reverse solubility above 300˚F. Some plant personnel, especially in the power industry, have switched to a caustic (NaOH) feed to eliminate phosphate “hideout,” but great care is required with these programs to prevent caustic gouging of waterwall tubes. WebPhosphate hideout is the result of chemical reactions of sodium phosphate with iron oxides where the reaction products has low solubility in high operating conditions. As consequence, salt precipitation occurs.
