Abstract

Se describe una composición y un método para dispersar azufre, limpiar depósitos de azufre y minimizar la formación de espuma en un sistema acuoso. El método puede incluir añadir un primer dispersante de azufre para procesar agua que contiene azufre y dispersar el azufre. El primer dispersante de azufre puede incluir un poliglicósido de alquilo C5-C25. El segundo dispersante de azufre también puede añadirse al agua de proceso. El segundo dispersante de azufre puede incluir un polímero de ácido acrílico y ácido 2-acrilamido-2-metilpropano sulfónico.
