A Thermochemical Evaluation of the FlashPhos Process

A Thermochemical Evaluation of the FlashPhos Process

The EU project FlashPhos is taking a pioneering approach to recover phosphorus from sewage sludge ash in its elemental form (P₄). The process is already being implemented and tested at pilot scale, aiming to demonstrate a sustainable, circular alternative to Europe’s...
White Phosphorus: The Hidden Ingredient Powering Modern Life

White Phosphorus: The Hidden Ingredient Powering Modern Life

When people think of critical raw materials, they might picture rare earths, lithium, or even oil. But there’s one element quietly running the show behind the scenes of modern industry: white phosphorus (P₄). You won’t see it in shops or on labels, but P₄ is a...
FlashReactor Simulation with Integrated Slag Flow

FlashReactor Simulation with Integrated Slag Flow

Building on the simulation models presented in previous posts (Multiphase Flow Model, and FlashReactor and Refiner Simulation), which described sewage sludge combustion in the FlashReactor, the modelling efforts at TU Graz have recently shifted toward understanding...
