Acquisition of Thermophysical Data for the Optimization of a Hydrothermal Gasification process

Topic description

The material and energy recovery of industrial and household waste has become a major challenge in addressing the environmental and energy issues facing our society. Converting waste into valuable resources is fully aligned with the principles of the circular economy. Numerous processes have been developed to treat and valorize waste, including combustion, pyrolysis, pyrogasification and microbial degradation. Although highly effective, these technologies are not always suitable for highly aqueous feedstocks such as sewage sludge, manure, industrial sludges, or certain waste solvents.

Hydrothermal gasification is an innovative technology particularly well suited to this type of feedstock. It involves processing organic matter in an aqueous medium under high-pressure and high-temperature conditions, above the critical point of water ( bar, °C). In this process, the mineral fraction of the waste (salts, ash, and minerals) can be separated...
