Can Rusted Surfaces be Effectively Passivated to Reduce Further Corrosion Prasad Kalakodimi, Ph.D. and Raymond M. Post, ChemTreat, Inc. 2017
Abstract: The ability to protect rusted surfaces is of critical importance because a corrosion inhibitor rarely encounters a truly clean metal surface, except perhaps immediately after a chemical cleaning. In the study presented in this paper, advanced electrochemical methods including electrochemical impedance spectroscopy (EIS), cyclic polarization (CP), and open circuit potential (OCP) were used to evaluate the effectiveness of corrosion inhibitors in passivating rusted surfaces. The relative performance of several traditional and advanced corrosion inhibitors is provided together with a mechanistic discussion.
Modelling Lead and Copper Corrosion and Solubility Robert J. Ferguson, French Creek Software, Inc. 2017
Abstract: This paper describes a twofold approach to computer modeling of lead and copper corrosion, and the transport of the metals through the water distribution system. The soluble lead and copper transport through a distribution system is modeled based upon the maximum solubility of these metals over the temperature and pH range likely to be encountered from the water source, through the high end of the expected temperature range in hot water heaters and dishwashers. The impact of mixing water sources on solubility can also be modeled. An expanded version of methods developed by Dr. Shock of the US Environmental Protection Agency is used for the models for the solubility calculations. The ion association model calculations include the impact of phosphates and polyphosphate treatments on lead and copper solubility. Similar methods are used to determine the maximum soluble inhibitor concentrations in industrial and municipal systems. Corrosion rate models are developed and used for the prediction of lead, copper and mild steel corrosion rates. Generalized models are discussed as well as the development of models for a specific water source or blend based upon field and/or laboratory testing.
Simplifying Corrosion Control with a Safer Choice Inhibitor Eric Ward, Rivertop Renewables 2017
Abstract: It is well known that phosphorous-based corrosion inhibitors cause fouling with calcium if they are not adequately treated with a stabilizing product to prevent foulant precipitation. This shortcoming makes this stabilizing product an essential component of any phosphorous-based inhibitor program. In this paper, a new corrosion inhibitor will be presented that provides a single-component replacement for the aforementioned dual-component system. This new inhibitor can not only replace phosphorous-based inhibitors; it can simplify the traditional corrosion inhibition programs for mild steel. This new inhibitor performs well across a wide range of hardness conditions and pH values, it allows for the reduction of the product used to stabilize phosphorous-based inhibitors, and is an environmentally friendly alternative for corrosion control. It has also shown excellent compatibility with other commonly used corrosion inhibitive chemistries. To demonstrate this new corrosion inhibitors performance benefits, both laboratory and field performance data will be presented.
A Fresh Perspective on Controlling Yellow Metal Corrosion Jon Cohen, ChemTreat, Inc. 2017
Abstract: Current methodologies for using azoles to control yellow metal corrosion have existed for years with little advancement. Although these strategies have met corrosion rate requirements for a majority of industrial systems, there are still many failures due to corrosion of yellow metals. This paper will highlight some mechanisms of yellow metal corrosion, new data on the effects of halogens on azoles and a new control strategy.
Novel And Efficient Non Phosphorus Cooling Water Corrosion Inhibitor Mary Jane Felipe, David Fulmer, Corina Sandu, Bing Bing Guo, Khac Nguyen, Baker Hughes Inc. 2016
Abstract: Corrosion may cause deleterious problems in cooling water systems and typically, when poorly controlled, may lead to decreased plant efficiency due to loss of heat transfer or even equipment failure. Most industrial cooling towers utilize orthophosphate, polyphosphates or other phosphorous-containing water treatment programs as corrosion mitigation measures. However, the use of such corrosion inhibitors is steadfastly becoming the object of federal and local regulations due to phosphorous contamination of surface water. In this regard, this paper details the technological development of non-phosphorous corrosion inhibitor for use of cooling water systems. Extensive testing of the non-phosphorous corrosion inhibitor clearly shows excellent corrosion inhibition efficiency in a wide range of cooling water conditions including compatibility with oxidizing biocides. Remarkably, this non phosphorous corrosion inhibitor also performs in high chloride contain cooling water. In general, treatment programs in such highly corrosive cooling water conditions require high level phosphate to achieve acceptable carbon steel corrosion rate. This highly tunable technology allows for corrosion mitigation strategies in response to new corrosion challenges in cooling water system not only to meet more stringent environment regulations but also to address corrosive water systems.
A Novel Biocide for Cooling Towers Improves System Performance and Reduces System Corrosivity Chris Baron and Stephanie Hammond, Solenis 2015
Abstract: Traditional treatment programs for recirculating systems using strong oxidizing biocides often result in elevated general corrosion rates. A novel mild oxidizing biocide system that provides superior microbial control of cooling systems at considerably lower corrosivity has been introduced. The novel biocide is produced on site using dedicated feed equipment to convert a strong oxidizer, sodium hypochlorite, into a mild oxidizer that selectively targets mesophilic bacteria and algae without detrimental corrosive side-reactions. Typical performance improvements of cooling systems using this program include a substantial reduction in azole corrosion inhibitor feeds, increases in cycles of concentration, and decreased cleaning frequencies for condensers.
Restoration of Concrete Cooling Towers Damaged by Reinforcing Steel Corrosion Javier Balma and Dilip Choudhuri, Walter P. Moore 2014
Abstract: This paper describes the ongoing restoration of two reinforced concrete hyperbolic cooling towers that exhibited extensive deterioration due to corrosion of the embedded reinforcing steel. The cooling towers were constructed in 1983 and 1985 and are each 453 feet tall reinforced concrete shell structures. The restoration work included the removal and replacement of more than 200,000 square feet of concrete and the installation of an impressed current cathode protection (ICCP) system to protect the embedded reinforcing steel from corrosion. The cost of the restoration work is approximately $53 million.
Premature Failure of Open and Closed Recirculating Cooling Water and Fire Water System Piping and Equipment – Are you Responsible? Robert J. Cunningham, P.E., Arthur Freedman Associates, Inc 2014
Abstract: In recent years there have been a relatively large number of unexpected, premature failures of system water piping associated with HVAC, Process Cooling, and Fire Water systems in modern buildings designed for commercial, residential, health care, governmental, and manufacturing occupancy. Facilities designed to provide long term service live are failing due to severe corrosion resulting in complete penetration of circulating water piping as a result of severe pitting type attack. This corrosion is occurring on the water side in both galvanized and un-galvanized carbon steel and copper piping. It is not uncommon to encounter systems where complete penetration has occurred within 4 to 8 years after initial commissioning, even though it appears to the building management team that an appropriate water treatment program is in place. These premature failures are now finding their way into the courts, as attempts are made to determine responsibility and to seek compensation for these failures, resulting in severe reduction in asset value.
A Review of Solid-Form Scale and Corrosion Inhibitors Mike Hunter, APTech Group, Inc. 2014
Abstract: Solid form water treatment scale and corrosion inhibitors for cooling water systems have been on the market as an alternative to liquid chemistry for well over a decade. With that much use history in place, now is a good time to review the water treatment effectiveness, as well as the many “soft” advantages of Solid water treatment chemicals in the areas of safety, material handling, space-saving concerns, and shipping. This paper will examine the claims of Solid water treatment products to understand if they stand up to close scrutiny.
Microbial Corrosion on Metallic Surfaces Karoline Bohlen, Colorado School of Mines 2013
Abstract: The underlying conclusion to past studies on microbial corrosion is that it is a complex subject, still not yet well understood. It’s been found that many bacterial species can be part of the corrosion process, different metal surfaces show different progressions of corrosion, and microbes can also inhibit corrosion of the metals. There is no consensus as to the role microbes can play; it is quoted from varying sources that microbial induced corrosion is involved in the range of 2% to 90% of problem. This paper summarizes the process and proposes a simple research approach.
Prevention of Corrosion, Erosion and Abrasion in Cooling Towers Lake Barrett and Karl Sauereisen, Sauereisen, Inc. 2013
Abstract: Asset preservation is a major priority among utilities and communities. Within Cooling Towers, the forces of corrosion, abrasion, and erosion can have devastating effects. Changes in cooling Tower design and water treatment practices are, in some cases, elevating the exposure. The use of protective materials is becoming increasingly critical to extending the life of cooling tower infrastructure. Sauereisen will present multiple solutions for restoring and protecting cooling tower basins and any other vulnerable concrete or steel surfaces.
The Progression of Automation and Process Control for the Management of Open Cooling Water Systems Kevin Milici and Gary E. Geiger, GE Water & Process Technologies 2011
Abstract: Enhancement opportunities for cooling water systems can be placed into three major categories. The first is optimizing the dosing of specialty and adjunct commodity chemicals used for corrosion, scale/deposit, and microbiological control. Making sure the right dosage of the right chemistry at the right time avoids “overfeeding” for worst case situations. Once optimized, minimizing the variation greatly reduces the potential for failures that result in unscheduled shutdowns or impaired operations. Secondly, confidence from effective measurement and control enables the optimized use of increasingly scarce water supplies, and/or the ability to utilize lower quality, alternative water sources. Lastly, the productivity of personnel charged with operating cooling systems can be greatly enhanced. In recent years, much focus has been placed on online instrumentation and control while these advances are and will continue to be welcome contributions to users. This paper discusses the advent and merits of new and complimentary online and offline monitoring and control technologies, using case studies and practical scenarios as illustrations of their impact for users.

Cooling Water - Optimal Control of Admiralty Corrosion Utilizing Multiple Halogen Sources Gene Dombrowski, ChemTreat, Inc. and John Zimowski, Dupont 2007
Abstract: Effective copper alloy and steel corrosion control, along with effective fouling control, can be major challenges in industrial cooling water systems. Major issues include achieving effective chlorine and copper alloy inhibitor feed rates and proper residual control. This paper provides a case history that describes how monitoring of cooling water chemistry, corrosion monitoring, and fouling monitoring were used to achieve effective performance results under difficult conditions. Advantages of using bleach and activated bromide to subsidize the gaseous chlorine application are discussed. Some of the monitoring tools used to determine adequate treatment concentrations and to optimize performance with respect to chemical costs and avoided costs are described.
Corrosion-Induced Concrete Deterioration and Rehabilitation of Natural Draft Hyperbolic Cooling Tower Leandro Etcheverry, Corrosion Restoration Technologies 2007
Abstract: Since an environmental conductive to corrosion-induced deterioration exists in natural draft hyperbolic cooling towers, understanding of the deterioration mechanisms as well as effective rehabilitation strategies are required to preserve the value of natural draft hyperbolic cooling towers. Due to the progressive nature of corrosion deterioration, the consequences and costs associated with delaying repairs can be significant. By utilizing state-of-the-art concrete repair technology augmented with high performance construction materials and protection systems, cost effective repair programs can be implemented. These repair programs can extend service life and protect the value of the high initial investment associated with the construction of hyperbolic natural draft cooling towers.
New Liquid Biocide Products for Specific Industrial Water Treatment Requirements Christopher Nalepa, Albemarle Corporation 2007
Abstract: Liquid biocides continue to be a popular choice for control of microorganisms in industrial water systems and numerous treatment options exist in both oxidizing and non-oxidizing biocide categories. The purpose of this paper is to introduce a family of liquid biocides based on bromine chloride as the active ingredient. These products were developed with the requirements of specific water treatment segments in mind. Products are available for both the commercial and middle-market segments that deliver the convenience and consistent activity that is much valued in these market segments. Higher activity products were also developed for large-volume heavy-industrial applications that feature activity approaching that of fresh "off-the-line" bleach while still delivering the benefits of a stabilized bromine system. This paper will point out the unique features of this family of products and show comparative field and laboratory data to aid in proper biocide selection.

This program is in progress and additional data will be includes as it is developed.
Corrosion and Biofouling Control in a Refinery Cooling Water System Using Sewage Water as a Make-up. Abdulmohsen Almajnouni, Saudi Arabia Oil Company and Arif Jaffer, Consultant 2002
Abstract: Experience has shown that corrosion and biofouling control are important factors in operating a "clean" open evaporative cooling water system. Treated sewage water as make-up to the cooling tower requires novel approaches to control corrosion and biofouling besides meeting environmental regulations. An intensive field study was conducted to evaluate the effectiveness of a non-chromate treatment program. On-line cleaning of the exchangers occurred prior to instituting the new chemical treatment program. Low carbon steel corrosion rates with minimal deposition was achieved. Microbiological fouling was controlled with chlorination and non-oxidizing biocide program. Field tests are presented that compares the efficacy of these proprietary treatments to control corrosion and inhibit scale and biofouling. Analytical results are presented that provide a comprehensive evaluation program of a new non-chromate chemical treatment program.
Elucidation of Components of Aromatic Triazole Demand in Cooling Water Systems and Development of More Environmentally Friendly Yellow Metal Corrosion Narasimha M. Rao, Donald A. Johnson, Frank F. Lu, Nalco Chemical Company; N.P. Nghhiem, Oakridge Nat'l Laboratory 1997
Abstract: Concern about aquatic toxicity of cooling water discharges has driven the development of biodegradable inhibitors for use in cooling water treatment. Aromatic 1,2,3-Triazoles are important components of corrosion inhibitor package of most cooling water formulations. This paper examines the correlation between structure of aromatic triazoles and the ease of their biodegradation. The mechanism and kinetics of biodegration and the impact of structure-specific biodegradation rates of isomers on inhibitor consumption in power plant applications is discussed. The understanding of structure-biodegradability correlations has led to the development of new, more environmentally friendly yellow metal corrosion inhibitors, which also posses superior yellow metal corrosion inhibition performance. The properties of one of these inhibitors are discussed.
Cathodic Protection of the Palo Verde Cooling Towers William R. Schutt, Matcor, Inc. 1996
Abstract: This paper discusses the concrete damage due to the corrosion of the reinforcing steel in the nine cooling towers at this nuclear power plant. Although some conventional concrete repairs were tried, they were unsuccessful. The cause of the concrete damage was the corrosion of the reinforcing steel. After a series of tests and trial cathodic protection systems, a full-scale cathodic protection installation program was started. The paper documents the process and how the cathodic protection system is saving the owner almost ninety million dollars.
Analyzing Corrosion Rates of Copper for Open Recirculating Systems Gary Caplan, Diversey Water Technologies Ltd. 1996
Abstract: A Total Quality Management (TQM) Program consists of at least three topics: Quality Function Development, Quality Costs and Problem Solving Techniques. This paper reviews five problem solving techniques in order to solve the following problem: "Why are copper corrosion rates as measured by coupon so high in recirculating cooling waters?" The techniques used include brainstorming, flow charts, histograms, and papeto analysis and cause-and effect diagrams. Although copper was the metal of interest, these approaches can be used to study corrosion of other metals or to evaluate any other problem.

An Alternative Oxidizer, Bromine Offers a Northeast Chemical Plant Improved Corrosion and Fouling Control (TP-90-08) Mark J. Giusto, Drew Industrial Division 1990
Abstract: Chlorine was historically used as the oxidizing microbiocide at this location as it was considered the most economic alternative. Recent changes in state law, with respect to the storage of chlorine gas, forced the plant to review other oxidizing chemistries, which previously were considered economically unattractive. A trial was run on solid bromine releasing compounds and on activated sodium bromide. Change in corrosion rates and in the amount and type of suspected matter in the water was noted. Improved fouling control and reduction of corrosion rates of admiralty brass and mild steel resulted. Cost comparisons are made.
Reducing Copper Corrosion and Discharge Via a Novel Inhibitor and Applications Program (TP-89-01) Orin Hollander & Charles Shelton, Betz Industrial, & Ronald Griffin, City of Tallahassee Electric Dept. 1989
Abstract: The A.B. Hopkins Generating Station operates under severe copper discharge limits of 30 ppb at the discharge point.

A new proprietary inhibitor, which is feed for 10 minutes every 3 weeks to 5 ppm active reduced corrosion rates to 0.0w mpy and copper discharge to 20-25 ppb.
Investigation of Alternative Inhibitor Programs for Highly Corrosive Alkaline Waters (TP-89-11) Greg Simpson & Richard Murtagh, Burmah Technical Services, Inc. 1989
Abstract: The poor performance of a particular corrosion inhibitor package in an open evaporative cooling system resulted in increased efforts to find alternate inhibitors, which would give acceptable corrosion results. Through the molybdate-based inhibitor is used with very good results in other towers with similar waters the results in this tower were marginal to poor. A laboratory investigation was undertaken to assess the performance of a conventional HEDP-Zinc package and HEDP-Low Zinc package and a proprietary Phosphonate-Low Zinc (PPLZ) package relative to that of the existing program. This paper presents the results of both the laboratory evaluation and field trial that resulted.
Corrosive Water - A Brazilian Reality (TP-87-17) Jose Otavio Silva, Messias Candido Amaral & Flavio Bianchi, Aquatec Quimica, S.A. 1987
Abstract: In Brazil, for the majority of open recirculating systems, make-up water contains a low dissolved solids index and its main contaminants are aluminum and iron. The first one derives from raw water clarification process leakage; the latter may have the same origin and/or may be a product of equipment and lines corrosion. Iron and aluminum form a compound of low solubility product that may seriously affect the heat transfer. Considering these characteristics, treatment programs were developed. The high efficiency of these programs is due to "high performance" dispersants that assure a perfect performance for corrosion inhibitors and biocides. This paper shows four years well succeeded programs used at a crude refinery where-own process contamination (sulphide, hydrocarbon) generally effect negatively any treatment program applied.
