Mar 22, 2017 · Here small scale is defined as a plant scale of at most 2 MWe. Power generation in such small-scale plants requires biomass gasification technology in order to obtain higher thermal efficiency. Gasification is a process that converts carbonaceous materials into carbon monoxide, hydrogen, carbon dioxide, and gaseous hydrocarbons (producer gas).
The dimensions of the module of 60 tons built in the OMV refinery were 7.5 m x 7 m x 21.5 m (height) and it had 2,000 m of pipes. The cost of the project came to EUR 7 million. The results obtained under the various operation conditions showed that the up-scaling from a semi batch lab-scale reactor to a pilot plant was successful.
