For energy you can count on, our resin solutions will help reduce operational costs; maximizing your equipment reliability and power output.
Boilers need boiler feedwater treatment facility for efficient and quality steam generation. This facility helps to reduce boiler failures and maintenance costs. Water contains dissolved gas ions which increase corrosion and scaling. There are feedwater treatment systems types; deionization/softening, filtration & ultrafiltration, Membrane processes, deaeration/degasification are some of them. Depending on impurities, the treatment type can differ.
When using deionization or softening in water treatment, it is essential to select the correct resin type for the requirement. Problematic ions: bicarbonates, sulfates, chlorides, and nitrates necessary to remove and strong acid cation resins engage on duty. Both Strong Acid Cations and Strong Base anion resins are prominent in the field.
Condensate polishing is applied in the power industry. The ultimate goal is to remove all impurities in water and protect the high-pressure boilers. The process differs from the conventional ion exchange, but it is only one step of the overall process. Ion exchanging process exchanges contaminants with anions and cations with the action of synthetic porous resins. The resin mixture can consist of varying cation-to-anion resin ratios, depending on the number of dissolved contaminants expected, with 2-to-1 and 1-to-1 resin ratios being the most common.
Cooling towers are excellent heat exchangers by direct contact with air and water to reduce water temperature. A slight amount of water can evaporate, and water recycles within the system. So precipitations can be occurred in the system due to contaminants dissolving in water. The primary purpose of the water treatment system in a cooling tower is to generate ultrapure water for its process. Total dissolved solids (TDS), Total suspended solids (TSS), hardness, Iron, Organic matters, silica, Alkalinity, Sulfates, and chloride need to be eliminated. Depending on the water quality level, the ion exchange process can be used as a single unit, but a combination of other methods; filtration, sedimentation, chemical additions.
Demineralization/deionization produces purified water with the same quality as distilled water. These methods help to remove total dissolved solids (sulfates, nitrates, chlorides, other than hardness. The DI process can use one or more ion exchange columns. Strong acid cation resins and strong base anion resins in hydrogen and hydroxide forms convert their corresponding acids and bases, respectively. Mixed bed processes reduce the conductivity too. Reduction of regeneration cost, 90% reduction of slat concentration in large scale IX plants can be occurred using pre-treated water with some other technics. All four types of resins can use for Demi plants and DI plants. They are; Strong Acid Cation, Weak acid Cations, Strong Base anions, Weak Base anions.
Dissolved metal ions, Iron, Copper, will be a reason for corrosion of equipment & piping systems. Corrosion develops leakages, equipment damages, and loss of heat energy in many systems. It may cause high operational and maintenance costs. Cation, anion resins, and chelating resins involve removing metal ions from water and increasing the efficiency of condensate and boiler systems.
Resins play different roles in the biodiesel industry; catalysts, Biodiesel purification, and glycerin purification. Esterification, absorption, ion exchange are some steps that can be identified clearly. Cation exchange resin in H+ and Na+ forms can use as effective catalysts in biodiesel production. Ion exchange resins have many advantages; low cost, chemically stable, highly available, easy handling, adaptable at any reactor. Also, in purification steps, resins are more commonly used than water wash. It has a low operational cost, low energy, no water usage, low maintenance with a dry system. Strong acid cation is utilized for appropriate steps.
