GAP removes contaminants from Kraft process liquors while recovering valuable acid. Throughout the Pulp & Paper industry, chlorine dioxide (ClO2) is used in the pulp-bleaching process. ClO2 generators chemically convert sodium chlorate to chlorine dioxide and sodium sulfate in a strong solution of sulfuric acid. The acid is continuously purged from the generator in order to prevent the ...

As mills reduce the amount of effluents and emissions, they retain and recirculate more chemicals in their chemical recovery systems. Specifically, the accumulation of non-process elements such as potassium from the wood can cause corrosion and efficiency problems in the chemical recovery boiler. The challenge is to reduce or eliminate the potassium salts to manageable levels. Potassium is ...

Ion-exchange resins are used to replace the magnesium and calcium ions found in hard water with sodium ions. When the resin is in its regenerated form, it contains sodium ions at its active sites. When in contact with a solution containing magnesium and calcium ions (but a low concentration of sodium ions), the magnesium and calcium ions preferentially migrate out of solution to the active sites ...

Electrolyte from the Copper Liberator cells is directed to the Spectrum Filter to remove suspended solids by an automated, back washable filter with a permanent media. The filtered solution then flows through an Acid Purification system which consists of a proprietary ion exchange resin column where the electrolyte solution (sulphuric acid) is separated from the metal salts by the resin. A ...

Eco-Tec’s Salt Separation Unit (SSU) process employs a specialized ion exchange resin with high selectivity for chloride over sulfate and carbonate, as compared to conventional resin. The SSU operating cycle consists of two basic steps, loading and elution. During the loading step, the feed solution containing mixed salts is introduced to the ion exchange column. Chloride is preferentially ...
