OptiSperse* HTP boiler water dispersants
OptiSperse HTP boiler water dispersants represent a major breakthrough in iron deposition control for high pressure boilers and remain unmatched in the paper industry. Deposit control in boilers is critical to the reliable, economical operation of the powerhouse—and therefore of the mill. Waterside deposition impacts heat transfer efficiency and can lead to overheat or corrosion failures. Deposits cause the tube metal temperature to increase, which can lead to metal deformation and ultimately overheat failure. When deposits are present in the boiler, under-deposit corrosion can occur, which also leads to failure of the boiler metal.
Polymeric dispersants have long been used for boiler deposition control. However, most conventional iron dispersants lose their efficacy as boiler pressure increases. The limited efficacy of these dispersants under higher-pressure boiler conditions led to the development of OptiSperse HTP boiler water dispersants, which are specifically designed to remain stable and disperse iron under high-pressure boiler conditions. These dispersants maximize boiler reliability by providing superior iron transport as compared to conventional polymer dispersants.

Customer Analytical Services
Ashland Water Technologies’ Customer Analytical Services team is dedicated to helping customers address the multitude of contaminants that can negatively impact the efficiency and reliability of their water-based systems. The team is made up of an experienced staff of analytical chemists, microbiologists and technicians and is supported by sophisticated testing equipment that provides rapid analysis and identification of contaminants beyond what may be accomplished with field-based methods. Key services provided by the team include fluid analysis, deposit analysis, microbiological analysis and metallurgical analysis.
Corrosion Monitoring and Metallurgy
Problems related to corrosion cost commercial and industrial plants billions of dollars each year. Although a variety of means exist to inhibit corrosion, it's important to identify the root cause of the corrosion. Ashland Water Technologies’ Corrosion Monitoring and Metallurgy group provides failure analysis and assessments of steam-generating and heat-exchanger equipment. Working closely with customers, this team provides clear identification of the problem, which leads to a more rapid and effective solution. Key services provided by the group include failure analysis, corrosion coupon analysis, and elemental and compound analysis.
