Converting Waste Agricultural Biomass into a Resource - UNEP

synthesis gas cooling and conditioning process. Initial cooling of the gas is
accomplished with an indirect gas cooler. This is followed by direct contact
cooling. After the synthesis gases are sufficiently cooled, the gases are
mechanically cleansed of any residual entrained ash and aerosol tars.
Synthesis gases treated in the patented process are suitable as fuel for
internal combustion devices.

Environmental Considerations
However, in addition to this calorific content, the evolved gases contain ash
and tar contaminants. Until recently, these contaminants presented a
seemingly unsolvable problem. When consumed as a fuel in engines or
turbines, their presence damages and debilitates internal moving surfaces of
the engine or turbine.
Investment and Operating Cost
At Primenergy’s Tulsa location, there is a full commercial scale demonstration
gasifier. This gasifier has been retro-fitted with the gas cooling and cleansing
system. To demonstrate the proof of concept, olive waste from Italy was
imported. An internal combustion engine was installed and operated under
load.
Examples of Real Life Applications
