  • Marks’ Standard Handbook for Mechanical Engineers, Eleventh Edition > STEAM BOILERS
    However, steam condensate can be contaminated by corrosion products or by in-leakage of condenser cooling water . Where the returning condensate is contaminated to such an extent that it does not meet the feedwater quality requirements, mixed bed ion-exchange demineralization purifiers are used to remove the dissolved impurities and filter out the suspended solids. This is referred to as condensate polishing and is essential for satisfactory operation of once-through utility boilers where the feedwater requirements are especially stringent.
  • Cogeneration
    Externally supplied utilities are shown in Table 5.4 for study cases. The boiler produces saturated steam at 185 psia, from which 85 psia steam for process uses and … Furthermore, the 85 psia throttled steam is desuperheated to saturation by condensate injec- tion via a mixing tee, while the slightly superheated 25 psia steam is used in the deaerator directly. Boilerfeed water (BFW) is composed of a polished (i.e., finely filtered ) returned proc- ess condensate portion and a makeup fresh water portion softened by a packed bed process (S-lOlA,B).
  • Marks’ Standard Handbook for Mechanical Engineers, Eleventh Edition > CORROSION
    For high-pressure electric utility boilers , two-stage demineralization (e.g., cation/anion/ mixed bed ion exchange; reverse osmosis/membrane decarbonation/continuous electrodeionization, and combinations of these) is generally utilized. … of makeup treatment systems (Sheppard T. Powell Associated, LLC, “Revised Guidelines for Makeup Water Treatment,” TR113692 … … e.g., ≤15 psig, ≤100 kPa) boiler systems which receive large amounts of condensate return, but this … Condensate returns often require purification or polishing . Condensate polishing can be achieved with specially designed filters , softeners, or mixed-bed ion exchangers.
  • Crits Notes on Water and Ion Exchange
    In addition to this work, B & W produced Membrane Millipore Fil- ter Iron Oxide Stain comparison charts showing various black, brown, and yellow oxide values in condensate at the ppb level. In PWRs and fossil utility plants, the 2:1 by volume ratio was favored without reserva- tion … As a result of a sea water condenser leakage incident at Millstone Station and stricter limits on … – Mixed - bed condensate polishing is used in relatively higher-purity con- densates, those from boilers higher than 800 psi with the following puri- fication functions: .
  • Utilities Costs
    Utilities Costs, September 1980 In most boiler feedwater systems, the major portion of the feed- water is the returned steam condensate from turbine condensers and/or process heat exchanges. This water is relatively pure and requires only minimal treatment before it is recycled to the boiler. … or no treatment is given to the returned condensate; above 450 psig, a polishing treatment is normally … If the contaminants are predominantly suspended solids, a septum filter would be used. Dissolved solfds are generally removed in a mixed bed ion exchanger, designed for high throughput operation and up to 285OF.
  • Nalco Water Handbook, Third Edition > The Power Industry
    For the best cost performance, regenerable mixed bed polishers are commonly operated at service flow rates over 50 gpm/ft 2 (122 m 3/[h · m 2]), about 10 times the rate employed in raw water demineralization. Nonregenerable powdered resin polishers have found wide acceptance in utility systems. The finely ground resin particles provide good filtration and excellent kinetics for ion exchange. This type of condensate polisher is typically operated at service flow rates of about 4 gpm/ft 2 … Virtually all once-through boilers , because of their especially high-purity water requirements, employ polishing of feedwater.

All water for industrial use is extracted from this stage, but for boiler use, further treatment is … For high pressure boilers, water quality is very restrictive, so a supplementary ions removal is demanded, called polishing , using basically the same process of resin beds , but with a higher efficiency and deeper capture capacity. The main actions to reduce energy consumption are in condensate recovery and avoiding water losses in general …
  • Methanol
    The makeup water requirement of 4,500 gpm is divided 95% for process and utility cooling water additions and 5% for boiler feed makeup. If after suitable filtration or polishing , the process con- densates are recycled, the feedwater requirement is reduced by 700 gpm. as shown in Figure 6.3, is collected, polished by mixed bed ion-exchange and returned--via feedwater heaters--to the Koppers-Totzek gasifier and utility HP boilers.
  • Steam Plant Operation, Ninth Edition > Auxiliary Steam-Plant Equipment
    Also, in both utility and industrial applications, condenser leaks can allow cooling water to contaminate the condensate . Demineralized systems that are installed to purify condensate are known as condensate polishing systems. They are generally used in plants where boiler water chemical treatment and blowdown of solids will not … … condensate polishing system that uses precoat materials designed to provide the combination of filtration and ion exchange … … impurities to be removed is relatively low, precoat systems are preferred over deep- bed demineralizer systems because … Another type of condensate polisher is the deep- or mixed -bed type, which consists of a service …
