Dow Water Solutions Selected For China Ling Ao Nuclear Power Plant Phase II
Dow Water Solutions, a business unit of The Dow Chemical Company (Dow), recently announced that its DOWEX™ MONOSPHERE™ ion exchange resins 650C and 550A for condensate polishing, along with DOWEX™ MARATHON™ C, DOWEX™ MARATHON™ A and DOWEX™ MARATHON™ WBA series for brine cleaning will be installed at Ling Ao Nuclear Power Plant (Phase II), which is located adjacent to the Daya Bay Nuclear Power Plant, and together comprise one of the largest, total installed capacity nuclear power bases in China.
"DOWEX™ ion exchange resins have excellent mechanical and chemical resistance and have been running successfully in nuclear power plants for more than 15 years. Their exceptional performance in this demanding application is backed up by higher capacity, faster kinetics, shorter rinse time, and longer resin life," said Kelvin Cheung, DOWEX™ product marketing manager, Dow Water Solutions. "We are confident that our products can offer customers performance improvement in water quality and operational efficiency for deep-bed condensate polishers in nuclear power plants."
The deep-bed condensate polishing systems in pressurized water reactor (PWR) nuclear power plants filter corrosion products transported from the main condenser to help control secondary cycle steam generator chemistry. It requires complete separation of the mixed resin to improve effluent water quality. Excellent mechanical strength and oxidative stability are also desirable features for less release of high megawatt (MW) greater than 1000 total organic carbon (TOC) species from cation resin to help minimize downstream sulfate excursions.
With uniform particle size distribution and outstanding mechanical stability, DOWEX™ MONOSPHERE™ resins can help to achieve excellent cation/anion separation during regeneration, providing more thorough and effective regeneration and improved water quality with reduced resin cross regeneration, all of which help to increase the cost effectiveness of the system and the nuclear power plant.
China is accelerating the construction of nuclear power plants and raising the ratio of nuclear power to five percent of the total energy mix by 2020, according to the newly-formed State Energy Bureau (SEB). State-of-the-art technology will be needed to ensure higher capacity and longer lifetime performance of the plants.
"As part of Dow's 2015 Sustainability Goals, Dow has a long term commitment to energy efficiency and conservation. We will continue offering innovative products and solutions to realize alternative energy and reduce the use of carbon-containing material. Dow is also committed to providing high-performance and cost-effective solutions for nuclear power plants in China to help optimize operational efficiency," said Antonio Pavese, global marketing manager, Dow Water Solutions.
China Huadian Engineering Co. Limited will provide the two 1,000MW PWR power generating units for Ling Ao Nuclear Power Plant Phase II and will be put into commercial operation in 2010 and 2011, respectively, which will further relieve the pressure of electric power supply in Guangdong province.
