BREATH

BREATH converts the fuel materials into Syngas, and water, which are then used to produce electricity and heat. After the energy production, the exhaust gases from the process are processed in a second reactor, producing water and synthetic methane.

THE PROCESS

BREATH works by means of a reactor, in which the waste materials are fed, after shredding and coarse sieving to remove the inert fraction. 

When the process starts, the temperature at the bottom of the reactor reaches around 1250° C, sublimating the waste materials to obtain synthetic gas (Syngas). 

The Syngas is filtered to remove the particulate matter, the humidity and the non-carbon compounds. If the desired composition is not reached after the filtration, the Syngas is sent back to the reactor to repeat the process. 

The humidity extracted from the Syngas is filtered and conveyed in a collection circuit as condensation fluid. A part of the liquid is employed to sharply decrease the temperature of the Syngas exiting the reactor, to avoid the formation of harmful dioxins. 

After the filtration, if the desired composition is achieved, the Syngas is fed into an internal combustion engine, which produces electricity. 

Part of the condensation fluid is used in the heat exchangers to recover the thermal power generated during the reactor activity. Through this process, steam and hot water are produced. 

BREATH works by regulating the process speed in order to always reach an energy production target of 125 kWeh & 235 kWth at regimen.

The excess condensation fluid can be used for industrial or agricultural purposes, but the remaining part of the condensation fluid is sent to the electrolyser units, which produce hydrogen (H2). 

At the same time, the post-combustion gases originating from the engine are conveyed to a catalyst, which sequesters the carbon dioxide (CO2). 

The CO2 and the H2 are then sent to a second reactor where, by making use of Sabatier’s reaction, methane (CH4, purity >92%) and water (H20) are produced.

The remaining fraction of the post-combustion gases (N2, H2O) is then released in the environment.

OPERATIVITY

VERSATILE BREATH is suited for compact configurations, as it is designed to fit in a 40’ container.
It does not require special placement, as the entire process is carried out at 0.5 bar to avoid explosion risks.
REMOTE CONTROL Once started, the process is self-maintained and self-regulated thanks to PLC control, enabling to maintain the process rate regardless of the starting material composition.
Sensors at each component level enable us to constantly monitor the process from remote.
ALWAYS ACTIVE Thanks to its redundant design, BREATH can operate uninterrupted for 8400 hours per year, as it remains fully functional during the ordinary maintenance.
