Decomposition of struvite

A method for decomposing struvite comprises dissolving of a feed material comprising struvite in a mineral acid. Thereby a solution having an acid pH is formed. Magnesium is removed from the solution. The removing of magnesium comprises increasing a pH of the solution to a pH in the range of 4.5 to 6, precipitating magnesium compounds that do not comprise ammonium, and separating the precipitated magnesium compounds from the solution. Thereby, the solution, after the removing of magnesium, comprises an ammonium salt of the mineral acid. An arrangement for performing such a method is also disclosed. Also, a method and arrangement for recovering at least nitrogen from waste material, based on the decomposing of struvite are disclosed.

A method for concentration of phosphate compounds comprises dissolving (205) of sludge ash in hydrochloric acid. Insoluble residues are separated (210), thereby forming a first leach solution. A mole ratio of phosphorus to a sum of ferric iron and aluminium in the first leach solution is controlled (215) to be larger than 1. A base is added (220) to the first leach solution in an amount causing precipitation of phosphate compounds. The precipitated phosphate compounds are removed (225) from the first leach solution. Sulphuric acid is added (240) to the first leach solution, causing precipitation of sulphate compounds. The precipitated sulphate compounds are separated (245) from the first leach solution. At least a part of the leach solution is recycled (248) as the hydrochloric acid used for the dissolving of sludge ash. Further methods for processing the precipitated phosphate compounds are presented as well as arrangements for performing the methods.

Preparation of liquid fertilizers with improved storage properties

a method for improving the storage properties of liquid fertilizers made from wet-process phosphoric acid. The wet-process acid is essentially defluorinated so that when it is processed by ammoniation to make high-analysis ammonium polyphosphate liquid fertilizers, the sometimes almost immediate precipitation of undesirable sludge compounds of magnesium does not occur in the liquid over long periods of storage. The liquids may be produced by dissolving hot ammonium polyphosphate melts directly as it is produced or by dissolving dry granular solid ammonium polyphosphate made from this type acid. Both ammonium polyphosphate and urea-ammonium polyphosphate base solutions made from defluorinated wet-process acid are highly stable and they exhibit increased tolerance for higher magnesium and lower polyphosphate levels.

Process for the production of ammonium/potassium polyphosphate compounds from potassium chloride and phosphoric acid feedstocks

The present invention relates to a continuous ion exchange methodology for production of ammonium-potassium polyphosphate solutions using agricultural grade phosphoric acid, anhydrous ammonia, and agricultural grade potassium chloride (ag potash) as primary feedstocks. The method is particularly applicable to the production of these low salt index, specialty liquid fertilizer solutions and allows for the use of less expensive ag-potash and impure phosphoric acid as the potassium and phosphate sources in order to produce the ammonium-potassium polyphosphate compounds, which are chloride free as a result of the ion ex-change process.
