APPLICATIONS & SOLUTIONS
Water and energy are inextricably linked through the water-energy nexus. All power plants, nuclear or fossil, need large volumes of purified water for cooling. Power generation accounts for 10% of all global water withdrawals, including 50% in US and Western Europe and over 80% in China. Energy is in turn needed to treat the wastewater from power plants so that it can be safely returned to the environment. Rapid industrialization and the need for electricity, along with growing water scarcity, demand new solutions.
Jacobi helps its customers reliably and cost-effectively generate electricity from fossil and nuclear power sources. Our experts will assist you in developing a sustainable solution for managing the critical water operations at your plant, such as boiler feed, condensate, makeup/reuse, and wastewater streams.
SUMMARY
- Make-up water demineralization
- Condensate polishing
- Condensate de-oiling
- Wastewater treatment
Fossil Power
Coal fired and natural gas plants rely on high-quality water to convert thermal to electrical energy. Make-up water requirements are very stringent for once-through, supercritical and ultra-supercritical fossil power units. Corrosion and fouling can lead to catastrophic turbine blade cracking and tube failure. Jacobi products deliver reliable, stable operation for uninterrupted power supply in all types of fossil power station and water sources.
Nuclear Power
With 445 reactors worldwide and 50 under construction, nuclear power generates nearly 30% of the world’s low-carbon electricity. Pressurized water reactor (PWR) designs cover two-thirds of all installations and consist of a contained primary heating-fluid circuit, a steam-producing secondary circuit, and a third cooling circuit. Boiler water reactor (BWR) designs are like fossil plants, except they operate at lower temperatures for safety reasons. High levels of makeup water purity are required to prevent catastrophic failure. Jacobi’s nuclear-grade Resinex™ products endure high water purity and our technical expertise supports the reliable and safe operation of nuclear reactors globally.
Jacobi’s Resinex™ line offers a full set of IEX solutions for both fossil and nuclear power stations and are compliant with the stringent specifications of process water and recycled condensate in power plants.

POWER GENERATION: PRODUCTS
Strong Based Anion
Strong base anion resins are bead sized co-polymers (mainly polystyrene-divinylbenzene) with a tertiary or quaternary ammonium group which removes anions in various processes. Resinex SBA comes in gel or macroporous type and is available in different bead sizes.
Strong Acidic Cation
Strong acidic cation resins are bead sized co-polymers (mainly polystyrene-divinylbenzene) with a sulfuric group which attracts cations. Resinex SAC comes in gel or macroporous types and are available in several bead sizes to adapt to different applications.
W A C
WAC are polyacrylic, gel or macro ion exchange beads. They have the unique carboxylic acid functions.
Weak Based Anion
Weak base anion resins are bead sized co-polymers (mainly polystyrene-divinylbenzene) with tertiary ammonium groups, which are usually macroporous in structure.
Inert Resins
Non-functionalized inert media made from Polypropylene or Polyethylene.
Mixed Bed Resins
Composed of strong cationic and anionic ion exchangers based on a polystyrene-divinylbenzene matrix.
