Abstract Phosphorous contained in the by-product sludge from phosphorous production is converted to sodium phosphinate via alkaline digestion in an agitator reactor. The digestion suspension product contains contaminants from the sludge and is, therefore, filtered prior to further processing. The liquid resulting from centrifugation is recycled to the process. Phosphine and hydrogen off-gases from the reaction are utilized in the production of phosphoric acid (combustion to H3PO4, mist absorption in circulating phosphoric acid).
