The Next Generation in Cooling Water Scale and Corrosion Strategy

Premier Water & Energy Technology, Inc. introduces the next generation in Cooling Water Scale and Corrosion Strategy. Premier 2200 specifically addresses issues of sustainability and cost by:

  • Reducing water consumption and expense,
  • Providing for resource optimization, and
  • Shrinking the physical and environmental footprint of Water Treatment Programs

By combining synergistic deposit inhibitors in a single formulation, Premier 2200 offers unparalleled levels of protection against calcium, silica, phosphate, iron, sulfate, carbonate and other mineral deposits. At the same time cathodic, anodic, and non-ferrous inhibitors allow 2200 to protect system components from the adverse effects of corrosion. This is all accomplished through the strategic combination of multiple anti-scalant and corrosion inhibiting technologies. In an industry first, Premier 2200 overlaps these technologies to provide a matrix of protection for cooling systems.

Successful in preventing deposition formation and inhibiting corrosion at 25%-75% the feedrate of traditional products, Premier 2200 allows for a smaller physical footprint and reduced handling and inventory requirements.

One of the unique characteristics of Premier 2200 is its ability to tolerate uncommonly high levels of mineral loading in cooling water applications. Premier 2200 has higher thermal stability and better oxidant tolerance than any product of its type available today.

Premier 2200 is raising the bar in operational cycles of concentration, water conservation and control.

Premier 227 represents a new approach to controlling scale and corrosion in Evaporative Cooling Systems. Developed and refined over several years, 227 introduces reaction based technology to an arena where residual treatment programs have been the norm for decades.

The development goals for 227 included high-cycle, hard water capability, improved results in the most difficult waters, ease of use and favorable environmental profile.

Using Premier 227 technology, potential scale forming minerals are reacted to form acetate compounds. These compounds are significantly more soluble than those formed by traditional treatment technologies.

Premier is committed to innovation and bringing to market alternative treatment strategies that yield efficiency, safety and environmental advantages over present technologies. One of the areas we are focusing on is non-traditional Microbiological Treatment options for Evaporative Cooling Water systems. One of the most promising of these is the use of On-Site Treatment Generation of chemistries that are effective against algae, slime, bacteria, fungus and other micro-organisms.

On-Site Treatment Generation eliminates handling and disposal issues and, in some cases, provides for treatment alternatives that have no environmental effect.


Deposits are the root cause of most boiler waterside problems. Deposit restrict the transfer of heat from the source to the water, often leading to boiler tube overheating failure. In addition, deposits are usually the root cause of on-load boiler corrosion, providing a site where non-corrosive boiler water concentrates into either a highly alkaline or acidic solution that corrodes the tube metal beneath the deposit.

There are many factors that affect the potential for boiler deposition. One of the major factors is boiler feedwater purity. The presence and quantity of hardness, iron, copper and silica in the feedwater greatly influences the potential for boiler deposits to form. Some other factors that affect the potential for boiler deposit to form include boiler operating pressure, heat flux, minimum water/steam circulation ratio and tube design. Since each of these factors can significantly affect the potential for boiler deposit formation, it is important to consider each of them when selecting the deposit control treatment products to be used.

While Phosphates and Chelants remain boiler water treatment mainstays, the emergence of high performance synthetic polymers offers an effective deposit control alternative. For example, polyacrylate (PAA), polyacrylamide (PAM), and polyacrylate-acrylamide (PAAM) perform as effective hardness and iron dispersants when fed with phosphate treatment and as fairly strong complexing agents when used as an “all polymer” treatment. As with EDTA, properly applied, PAA, PAM, and PAAM are good deposit control agents.

Polymethacrylate (PMA) is another polymer that functions as an effective hardness dispersant when fed with phosphate. When used with carbonate or as an “all polymer” treatment the complexes formed with feedwater hardness and iron contamination are not as strong as those formed by PAA and PAAM. However, when properly applied, PMA is effective for controlling deposits and there is a substantially lower risk of feedwater, economizer and boiler corrosion from product overfeed.

Polyethyleneglycolallylether (PEGAE) can also provide effective control of feedwater hardness and iron deposition in boilers operating at pressures up to 900 psig.

PAGAE is especially well suited for application to low-pressure boilers with high purity feedwater, such as plants with reverse osmosis – sodium zeolite softened or demineralized make up water. This is because PEGAE provides effective control of deposition from low level feedwater contamination and the potential for feedwater line and boiler corrosion due to polymer overfeed is very low compared to other treatments.

These and other all polymer treatment strategies are giving boiler operators new options in effective deposit control. To select the deposit control chemistry that will best enable the boiler plant operator to achieve long term, reliable operation, the characteristics of each individual chemical should be considered in view of the plant operating conditions.

Polyamine is a term commonly used in technical and commercial literature to describe a new class of boiler treatment technology. It is one of the key active components in the program, specifically a multifunctional, volatile, organic amine corrosion inhibitor.

As a boiler treatment, a Polyamine program is designed to provide protection against metallic corrosion throughout the boiler system. This includes feedwater, boiler, and steam condensate surfaces when it is fed at a single point in the system, normally to the boiler feedwater in the deaerator storage section.

The benefits of using a polyamine program include:

Simplicity – Complete system coverage and distribution from a single liquid treatment fed at a single feed point.

  • This includes system-wide protection against both dissolved oxygen and acidic corrosion from the blend of volatile corrosion inhibitors without the feed of multiple products.
  • Polyamine products are designed to be used in combination with standard internal boiler treatments, including polymeric dispersants, phosphates, and combination products.

Convenience – Program simplification in that two, or in some cases, three separate products can be replaced by a single Polyamine product.

  • Simplified, lower-cost single product feed system
  • Reduced product inventory and handling

Dependability & Assurance

  • Polyamine technology reduces the potential for both dissolved oxygen and carbonic acid corrosion failures in the boiler feedwater and steam condensate systems.

Reduced Total Cost of Ownership

  • A Polyamine program can often reduce overall treatment costs by eliminating the need to feed, inventory and monitor separate oxygen scavenger and neutralizing amine products
  • A significant aspect of the cost reduction equation is the efficient recycle of both the Polyamine and neutralizing amine corrosion inhibitors with the steam condensate when that steam is returned as boiler feedwater. Many dissolved oxygen scavengers, such as sodium sulfite, are entirely non-volatile. Thus, they provide no protection of the steam condensate surfaces, and are lost entirely to the boiler blowdown.

The basic program consists of the multifunctional organic amine corrosion inhibitor – the Polyamine – in combination with a specific blend of volatile organic neutralizing amines. The primary function of the Polyamine component is to adsorb at the metal or metal oxide surface, restricting the access of aggressive species such as dissolved oxygen, carbonic acid, chloride and sulfate anions, to the metal surface. The volatile neutralizing amines in the Polyamine treatment perform their normal function, neutralizing acidic contaminants, and elevating the pH into the alkaline range, where the protective metal oxides are most stable and adherent.

Polyamine technology will provide very effective protection against dissolved oxygen corrosion in boiler systems equipped with an efficient thermal deaerator. A Polyamine program produced superior corrosion control even at higher levels of dissolved oxygen. Polyamine technology is not recommended for application in systems which are not equipped with a thermal (or pressure) deaerator.
