Glatt Ingenieurtechnik will be presenting a market-ready process at POWTECH that fulfils the legal obligation of German waste disposal companies to recover phosphorus. In the first step of the two-stage “PHOS4green” process, a suspension is produced from the phosphate-containing ash, a mineral acid and, depending on the objective, other components. The suspension is then spray granulated in the fluidised bed. This results in fertiliser granulates that are available to plants and soil, which can be discharged, filled and delivered directly after the desired grain size has been reached.
From improving durability and flowability through dust reduction to a pronounced depot effect or a targeted nutrient supply via better active ingredient distribution, fluidised bed technology can deliver many benefits. The shape and size of the fertilizer granules can be determined within a defined range. The quantity of fertilizer components delivered to the soil can be adapted optimally, and significantly higher product qualities can be achieved. Solubility and protection against external influences can also be markedly improved.
Hot one-pot process – high temperature fluidized bed for simultaneous particle formulation and functionalization.
The requirements for the high-performance materials of the future pose new challenges for product developers: Innovative applications require increasingly complex materials, but their desired properties can so far only be achieved in cost-intensive multi-step processes. The process temperature plays a key role here. With high-temperature fluid bed systems, plant manufacturer Glatt overcomes previously applicable temperature limits and enables the production of catalyst materials in a single-step process.
