Abstract: Nonylphenol ethoxylates (NPEs) have been used as surfactants in a wide variety of household products and industrial applications. Despite their effectiveness as surfactants, NPEs can accumulate in the environment and adversely affect aquatic organisms. The dispersants of the present disclosure can be used to disperse oil and/or microbes while avoiding the adverse effects of NPEs. Oil and microbial fouling is of particular concern in refinery cooling towers where the water may be contaminated with oil and microbial growth can cause cooling inefficiencies among other problems. The dispersant may include an oil dispersant comprising a C6-C20 alcohol ethoxylate, a bio-dispersant comprising a copolymer of ethylene oxide and propylene oxide, and 2-butoxyethanol. The oil dispersant, the bio-dispersant, and the 2-butoxyethanol form a dispersant solution, and the solution does not include a nonylphenol ethoxylate.
