Condensate Polishing Solutions for the Power Generation IndustryInnovation for North America

Water Technologies

Today‘s power producers are under pressure to reduce costs and increase efficiency. Condensate polishing can help improve your bottom line by reducing the losses or damages caused by corrosion and deposits. Condensate treatment can significantly reduce start-up times and the frequency of routine cleanings. Siemens offers a wide range of condensate polishing solutions including deep-bed condensate polishers, condensate filters, special resin grades, off-site regeneration and mobile services.

Our breadth of technology, systems and services, combined with years of experience in designing, installing and operating deep-bed condensate polishing translates into cost savings and greater operating efficiencies for our customers.

Reducing Costs, Improving Efficiencies Condensate polishing improves water/stream chemistry, resulting in:

� Faster startups, improved online time and profits

� Extended power generation asset life

� Reduced heat loss due to fouling of heat transfer surfaces

� Improved efficiency of steam turbine and therefore power output

� Reduced chemical cleaning frequency

� Decreased steam generator blow down, reducing heat loss

� Ability to operate with small condenser leaks and air in-leakage

Maintaining High Purity with Deep-bed Condensate Polishing Deep-bed externally regenerated condensate polisher systems use cation and/or mixed-bed to filter out corrosion products generated in the thermal cycle and to remove any trace dissolved minerals that may enter the steam cycle.

Siemens offers the Fullsep™ deep-bed condensate polishing system to control resin cross-contamination (traces of cation resin in the anion resin after separation or vice versa), which can occur when the resins are being separated for regeneration. These resin traces become both exposed to and fully converted to the chemical in which they are immersed during the dosing processes. In the pure-water environment of the condensate cycle, this contamination can be released into the condensate. With Fullsep™ technology, resin cross-contamination can be controlled to less than 0.1 percent cation/anion without chemically enhanced separation.

Condensate treatment is recommended for most power plants that use steam to make power. Condensate polishers will remove:

� Dissolved solids that result due to condenser cooling water/air intrusion

� Corrosion products that result due to air intrusion, in particular air-cooled condensers

� Certain suspended and/or dissolved impurities in return condensate from a steam host for combined cycle plants

The Condensate Cycle

Siemens is the leader in developing customized critical-application resin. Our experts will review your chemistry and cost needs, and provide you with the best Siemens brand resin to meet your performance criteria.

Mobile Resin Tankers are Convenient and Reliable If you want to eliminate the hassles and hazards of on-site resin regeneration, our mobile resin tankers can sluice out your condensate resin and transport it to one of our facilities for regeneration. We’ll replace the sluiced resin with our high-grade condensate resin to make sure your system stays up and running. Our convenient, reliable service network is available 24 hours a day, 7 days a week. And, with a mobile system, we assume responsibility for the storage, handling and disposal of hazardous chemicals, making your work environment safer.

With over 50 years of experience in condensate polishing for the power industry, we can design the most efficient, cost effective system for your plant. Utilities and independent power producers worldwide are using Siemens condensate polishing systems and services to keep their water treatment systems up and running, and their power plants operating at peak efficiency.

Regenerating the Condensate Polishing Resin When the resin in the condensate polisher exhausts, it must be regenerated. This process is most frequently performed on site; however, off-site regeneration is often considered, since it eliminates on-site waste handling and reduces site personnel requirements.

Off-site regeneration service is available at a number of Siemens facilities designed for regenerating condensate polishing resins. The resins are removed to a Siemens tanker truck at the site by our service personnel and then transported to our regeneration facility. This is often done as an exchange program when the tanker delivers a fresh bed to the site and removes an exhausted bed.

Siemens uses physical and chemical techniques to:

� Scrub the resins of suspended matter

� Hydraulically classify the media to allow separation and isolation of the cation and anion resin

� Regenerate the cation resin with acid and the anion resin with caustic

Then, after thorough rinsing, the cation and anion resin is mixed together for delivery to the respective site for reuse.

Our Resin Services Save You Money We offer a wide range of resin services designed to help you operate your plant more efficiently and cost effectively. As the largest distributor of ion exchange resins in the U.S., we can replace your resin on short notice. With major distribution points across the country, we’re able to deliver resin wherever and whenever you need it, in a wide variety of packaging options.
