Abstract
A composition and method for dispersing sulfur, cleaning sulfur deposits, and minimizing foaming in an aqueous system is disclosed. The method may include adding a first sulfur dispersant to process water containing sulfur and dispersing the sulfur. The first sulfur dispersant may include a C-Calkyl polyglycoside. A second sulfur dispersant may also be added to the process water. The second sulfur dispersant may include a polymer of acrylic acid and 2-acrylamido-2-methylpropane sulfonic acid.
