Ion exchange for chloride and potassium removal in kraft mills
Electrostatic precipitator dust in Kraft mills often contains high levels of chloride and potassium, which can lead to boiler corrosion and require costly shutdowns. Efficient removal of these salts is critical to maintain operations and reduce maintenance costs.
Efficiently removes chloride and potassium from Esp dust.
The PDP™, PRU, and GAP Ion Exchange systems by Kovalus Separation Solutions provide advanced solutions for the selective removal of chloride and potassium salts in Kraft mills. Utilizing highly selective ion exchange resins, the PDP system targets chloride in electrostatic precipitator (ESP) dust, while the PRU system addresses potassium build-up in ash solutions. The GAP system, based on the APU® ion exchange method, separates sulfuric acid from sodium sulfate during chlorine dioxide generation. These systems enhance recovery of valuable cooking chemicals, minimize downtime due to corrosion and plugging, and ultimately lower both capital and operational costs. Specifically designed for the pulp and paper industry, these systems promote efficiency and sustainability in mill operations by reducing the need for chemical purchases and enabling continuous operation.
