Optimal design methods applied to solar-assisted hydrothermal gasification plants

Alberto Mian

The gasification of highly watered waste residues may help to reduce fossil fuels consumption, as well as emissions, all the while improving efficiency. The integration of supercritical gasification with solar energy may improve the performances of both ne ...

Cutting the cost of carbon capture: a case for carbon capture and utilization

Berend Smit, Johanna Maria Huck, Lennart Joos

A significant part of the cost for carbon capture and storage ( CCS) is related to the compression of captured CO2 to its supercritical state, at 150 bar and typically 99% purity. These stringent conditions may however not always be necessary for specific ...

Valorization of sugarcane biorefinery residues using supercritical water gasification: A case study and perspectives

François Maréchal, Alberto Mian, Adriano Viana Ensinas

The present study evaluates the use of supercritical fluid technology, particularly supercritical water gasification (SCWG), to add value to residues from a sugarcane biorefinery that produces first and second generation ethanol. This case study aims at el ...
