24. Biomass intermediate pyrolysis pilot plant

Brand and model:In-house manufacturing.

Capacity:20 kg/hour.

Description:The intermediate pyrolysis pilot plant consists of a rotary furnace operating under an inert atmosphere, constructed from Nigrofer 3220H ASTM B steel. The energy required for the pyrolysis reaction is provided by ten liquefied gas burners. The char generated in the process is collected in bins at the furnace outlet, and the gases are directed to a hot sintered metal filter (20 microns) to separate particulate matter. Afterwards, the gases pass through heat exchangers, where they are partially condensed and the bio-oil is recovered. The non-condensable gases are burned in a flare.
