Abstract

Un método para inhibir la formación de incrustaciones de sílice y silicato mediante el tratamiento de un sistema acuoso que contiene sílice con una cantidad eficaz de un agente quelante mezclado con un dispersante polimérico en un intervalo de relación en peso de más de 1.0:0.5 a menos de 1.0:3.0, agente a dispersante, incluyendo mezclas en una relación en peso de 1:1. Específicamente, el agente quelante es EDTA o DTPA, mientras que el dispersante polimérico es un dispersante derivado de óxido de alquileno y ácido.
