Latest Patents
Among his latest inventions are two significant patents that address critical issues in the cellulose pulp mill industry. The first patent involves a method for inhibiting scaling in alkaline waste liquor evaporators. This approach effectively minimizes calcium carbonate scaling in multi-stage alkaline waste liquor evaporation plants within chemical cellulose pulp mills. The process involves treating calcium-containing effluent from the bleaching plant concurrently with alkaline waste liquor, followed by heating and retention to significantly reduce dissolved calcium levels, ultimately leading to efficient evaporation with minimal scaling.
The second groundbreaking invention focuses on a method for removing nitrogen oxides from recovery boiler flue gases. This innovative technique utilizes a peroxide solution that, when contacted with flue gases, converts a substantial portion of the nitrogen oxides into nitrogen dioxide in a cost-effective and environmentally friendly manner. This method not only addresses emissions but also repurposes the resulting nitrates as nutrients for biological effluent treatment plants within the pulp mill.
