FINFuture - Fleksibilitet for fremtidige råvarer for gjødselproduksjon via nitrofosfat prossessen

Offentlig prosjektsammendrag

Yara is one of the world's largest producers of NPK fertilizers. Disruptions in the phosphate raw material supply chain due to the invasion of Ukraine has decreased the availability of high quality phosphates. To maintain production using lower quality phosphates, the nitrophosphate process must be transformed through process innovation built on new knowledge from R&D. The project will develop innovative methods to mitigate challenges due to lower quality raw materials, primarily thickening of process liquors. A deeper scientific understanding of the rock mineralogy can identify the root causes of thickening, and help develop mitigation methods. Several approaches for mitigation will be tested at laboratory and pilot scale. The feasibility of the most successful methods for plant scale will be evaluated. The implementation of these process innovations will increase strategic independence in phosphate sourcing, increase process robustness, and decrease the environmental footprint.
