Is Hydrochloric Acid or Phosphoric Acid Better for Scale ...

Phosphate ions can combine with calcium ions to form calcium phosphate, a highly insoluble compound. Because it can increase phosphate concentration and is a weaker acid, phosphoric acid is a less effective scaleremoving agent than hydrochloric acid. Hydrochloric acid or sulfuric acid are more commonly used for industrial scale removal.

Causticizing residues have three components: lime mud, green liquor dregs, and slaker grit. Lime mud (calcium carbonate and water) is burned in a lime kiln to regenerate the byproduct to lime (CaO). This byproduct may also contain unreacted calcium hydroxide, unslaked calcium oxide, magnesium, and sodium. The lime mud is about 70% to 80% solids.
