Abstract

The present invention concerns a process and an apparatus for purifying a phosphate containing acidic solution comprising impurities through a nanofiltration station comprising a number of nanofiltration membrane units, each comprising a retentate side and a permeate side separated by a membrane, the process comprising feeding the phosphate containing acidic solution through an entry line to a first membrane unit of n 2: 1 membrane units arranged in series, wherein a nth permeate flowing out of the nth membrane unit forms a nanofiltered phosphate solution. The gist of the present invention is the provision of at least one permeate recirculation loop, branching off the retentate side of the first membrane unit and closing the loop at the entry line to combine at least one of three permeates with the phosphate containing acidic solution.

Abstract

The invention relates to a method and device for producing a solution of polyphosphoric acid from a feed solution P0 by the wet method. An enriched phosphoric acid solution optionally mixed with a direct feed solution is pulverised in a flame of a combustion chamber in order to form the polyphosphoric acid solution. The combustion gases from the combustion chamber are placed in contact with the feed solution in a gas-acid contactor in order to increase the temperature and the P2O5 concentration thereof and thus to form an enriched phosphoric acid solution. A portion of the enriched phosphoric acid solution is conveyed with a flow rate of Qp into the combustion chamber in order to be pulverised in the flame. The rest of the enriched phosphoric acid solution is conveyed into a recirculation loop in order to be reinjected into the gas-acid contactor with a flow rate of Q2. The ratio of Qp / (Qp + Q2) is controlled with a predefined value.
