Patent abstract
Two intermediates that have known separate efficacy for preventing scales such as calcium carbonate, magnesium carbonate and barite (barium sulfate) were discovered to have a synergistic effect for preventing or inhibiting silicate scaling when used together. Each of these intermediates is ineffective at preventing silicate scaling when used alone; however, when used in combination, they have a synergistic benefit. In one non-limiting embodiment the components include a polyamine phosphonate and a lysine tetra(alkylene)phosphonate.
