  • Challenge #3 - Power Industry, Condensate Polishing

    A University installing new turbines for their expanded power plant was adding a new Cogeneration Facility, and needed to replace their existing water treatment system. The project required demolition of the existing system, temporary water service for their existing boiler feed equipment, and full treatment of water to produce 240,000-lb/hr steam. The system design had to be flexible enough to ...

  • Sulfate ion (SO42−) release from old and new cation exchange resins used in condensate polishing systems for power plants

    In this study, a dynamic cycle test, a static immersion method and a pyrolysis experiment were combined to examine the characteristics of SO42− released from several new and old cation exchange resins used in condensate polishing systems for power plants. The results show that the quantity and velocity of SO42− released from new and old resins tend to ...

  • Condenser performance optimization and life extension case study

    In 2007 Intek was presented with performance enhancement requirements imposed on an existing Westinghouse condenser. The objective was to determine if the condenser performance could be improved from design capability and to estimate the achievable amount of improvement. The principal drivers for the retrofit were load limiting conditions in the summer time and a desire to switch tube material ...

  • A connection between cycle chemistry and condenser configuration: part II

    Abstract Air in-leakage into the steam space of a condenser can become stored in pockets of high partial pressures that negatively impact condenser performance and become a source of dissolved gases in the feedwater. These pockets can be configuration caused and generally cannot be eliminated by reducing air ingress or increasing venting capacity. Fortunately, engineering designs are ...

  • HS-200 Lowering company costs and liability

    A major printing company was experiencing difficulties with managing their wastewater treatment system due to a higly concentrated oily water influent. The grab samples performed by the local sanitary district exhibited high levels of BOD, COD and oil and grease levels in the discharge water. The problem was traced back to their compressor condensate discharge. The company has ...

  • Mechanical vapour compression desalination plant at Trombay

    Desalination plants based on Mechanical Vapour Compression (MVC) technology are inherently the most thermodynamically efficient. The thermodynamic efficiency of the MVC process is derived from the application of the heat pump principle. A single unit of a two-effect MVC desalination pilot plant of 50 m?/day capacity has recently been commissioned at Trombay, Mumbai. The desalination unit is very ...

  • Power Industry using Micro-Media Filtration and short-bed ion exchange

    With the demand or higher efficiencies, lower maintenance and operating costs for boilwers and turbines, high-purity water treatment systems are becoming more crucial to the operation of power plants. Modern power plants, operating at supercritical and ultra upercritical boiler pressures and temperatures, require high-purity water that approaches quality levels at the theoretical levels. ...

  • How to Choose the Best Boiler Feed Water Treatment Technologies for Your Plant

    When it comes to choosing technology for boiler feed water treatment, knowing the feed water source quality in relation to the water quality required for your specific boiler is essential, as inadequate water treatment can lead to the scaling, corrosion, and fouling of the boiler and downstream equipment. We’ve mentioned this before in some of our previous boiler feed water treatment ...

  • Refinery remediation: fuel recovery and recycling

    Introduction The site is a former refinery that occupied approximately 64 acres of land in West Texas. Refinery operations produced all grades of gasoline, tractor fuels, diesel, distillate products, and fuel oils and operated between 1939 and 1954. As a result of past waste management practices, releases to soils and ultimately ground water occurred, resulting in the formation of a ...

  • Power Plant Improves Operating Efficiency with Culligan Matrix Solutions

    Challenge A large chemical manufacture was challenged with boiler tube failures in its power plant, resulting in costly repairs and down time. The boiler tube failures were a result of the incoming water quality to the power plant. Until recently, the boiler make-up water was treated with a combination of carbon media filtration and softening. As a result less than 50% of condensate was ...
