1 Finex Tailor-Made Ion Exchange Resins for Water Treatment Tiia Aromaa, 2012

2 Finex in a nutshell Location: History: Kotka, Finland - Resin production at current location in Kotka was established by FinnSugar in Formation of Finex Oy in 1990 thru management buy-out - Hartwall Capital Ventures acquires majority position in 2011 Employees: about 45 Revenue: circa 7 million (2009) Export share: about 95 %

3 Finex Oy, Kotka

4 Finex products - Chromatographic resins for food industry - Special polymers for casting industry - Powdered and bead resins for power plants - Pharma resins - Other

5 Tailormade products for customers needs Finex products are optimized for each customer s needs and can be produced in a wide range of variations by adjusting the parameters, such as resin type mean particle size particle size distribution degree of crosslinkage ionic form cation/anion ratio in mixtures

Finex powdered resin mixtures for power plants Resins for condensate polishing in nuclear and conventional power plants Finex powdered resins are homogenous mixtures of strong cationic and anionic

6 Finex powdered resin mixtures for power plants Resins for condensate polishing in nuclear and conventional power plants Finex powdered resins are homogenous mixtures of strong cationic and anionic resins. Both are completely regenerated before size reduction so that the mixture is delivered ready to use. Powdered resins of Finex have low impurity content and good coating ability on candel filters. Finex produce powdered resins with various cation-anion ratios to suit customers' wishes.

7 Finex powdered resin mixtures for power plants Main products Ionic form Cation/anion ration Nuclear grade Conventional grade H + /OH - 1 : 1 CA850H CA750H 2 : 1 CA867H CA767H 3 : 1 CA875H CA775H NH 4+ /OH - 1 : 1 CA850N CA750N 2 : 1 CA867N CA767N 3 : 1 CA875N CA775N H + Pure cation C900H C800H NH 4 + Pure cation C900N C800N OH - Pure anion A800OH A700OH

8 Powdered resins and precoat filtration Candel filters are coated with very thin layer of filter media (precoat) Suspension is pumped through the filter and filter media Solids/removed matters of the suspension are sticked into the precoat material Precoat material is changed when pressure drop becomes too high

10 Precoat technology In precoat filtration powdered resins work as both mechanical filter and as an ion exchanger. This quarantees very effective removal of corrosion products, ions and other impurities present in the condensate (even ppb level). Precoat filtration is effective way to clean high flow rate (over 1 ton/second) condensates

11 Exchange time, s Precoat technology Particle diffusion depends on particle diameter Smaller bead size, higher surface area, more rapid diffusion Compared to standard bead size cation-anion resins, the kinetics of powdered resin mixtures is appr. 100 times faster. 8% SAC Particle size, mm

12 Finex bead resins for water treatment Bead resins are available as weak or strong acid cation and weak or strong base anion Finex bead resins have excellent mechanical and thermal stability Condensate polishing, softening, demineralization and water quality control Mixed bed resins 50C/50A 40C/60A

14 Finex Indicator Finex indicator is typically a gel type strong acid cation exchanger. It is used in water quality control applications. In the manufacturing process, the resin is injected with special purple indicator dye which reacts to the acidity within the beads. When the resin is exhausted, ph rises and resin colour change from purple to yellow.
