Abstract

AUNQUE LOS QUELANTES TALES COMO EL ACIDO ETILENODIAMINATETRAACETICO (EDTA) SE HAN UTILIZADO PARA PREVENIR LOS DEPOSITOS MINERALES EN EL AGUA DE CALDERA, POR SU ELEVADO PRECIO NO SE HAN UTILIZADO EN EL TRATAMIENTO DE AGUA DE REFRIGERACION. SE HA ENCONTRADO QUE SE PUEDE UTILIZAR UNA CANTIDAD RELATIVAMENTE PEQUEÑA DE UN QUELANTE EN COMBINACION CON UN AGENTE DE CONTROL DEL DEPOSITO DE MINERAL TAL COMO UN FOSFONATO PARA PREVENIR LA DEPOSICION EN EL AGUA DE REFRIGERADO. UN COMPUESTO IDONEO QUE INCLUYE UNA RAZON 4,5:1 EN PESO DE ACIDO DIFOSFONICO HIDROXIETILENO (HEDP) A EDTA MUESTRA UN EFECTO SINERGICO AL UTILIZARSE PARA LA PREVENCION DE LOS DEPOSITOS.
