Orgawatt®:
From biomass to generation of renewable energy
From
its existing technological base, Vérité has developed an
expertise in energy
production from biomass and organic waste gasification (pig manure,
poultry litter,
wood, WWTP sludge, refuse of slaughter-house).
Currently, Vérité is testing, on behalf of Litelis,
its sister company, a new type of
gasifier of Cemagref origin by building a 1MWe
industrial unit, due to start up at
the end of 2007.
Principle:
Gasification
is a thermochemical transformation in which carbonaceous
material
is broken down, in the presence of a reactive gas (air, O2, H2O, etc.),
to produce
a combustible gas rich in hydrogen and carbon monoxide.
It can be applied
very widely to all types of solid organic material
(wood, litter, refuse
of slaughter-house).
The combustible gas generated
can be used in boilers to produce heat or in
gas turbines or internal combustion
engines to produce electricity. This technology
reduces pollutant emissions (no dioxin
or furan) as well as solid waste.
Gasification is a high-performance process
at the technical, environmental
and economic level.
Technology of the Orgawatt® unit:
The
Orgawatt® process consists of a gasification reactor, a device to purify
and cool
the lean gas, a heat production system and associated equipment. Cogeneration
produces thermic and electrical energy simultaneously by the addition
of an
internal combustion engine or a gas turbine.
