Abstract
Un proceso para reducir o eliminar la formación de incrustaciones durante la producción de ácido fosfórico mediante un proceso húmedo que comprende agregar en cualquier etapa de un flujo de producción de ácido fosfórico mediante un proceso húmedo un reactivo seleccionado del grupo que consiste en i) polidimetilamina epiclorhidrina etilendiamina; ii) cloruro de polidialil-dimetilamonio; iii) poliamina funcionalizada con silano; iv) una poliamina lineal o ramificada de acuerdo con la fórmula (1), en donde n = un entero de 2 a 200; R¹ se selecciona entre H, C₁₋₁₂ alquilo y C₆₋₁₂ arilo; y R² se selecciona entre H, C₁₋₁₀ alquilo, C₆₋₁₀ arilo o un compuesto de fórmula (2); en donde R¹, R² y n son como se definió para la fórmula (1); y v) mezclas de los mismos; en una cantidad inhibidora de incrustaciones de desde 10 g a 1000 g por ton de ácido fosfórico.
