[Gasification] Dynamotive begins construction of modular fast-pyrolysis plant in Ontario

[Philippe Raufast]

    "Dynamotive Energy Systems and Evolution Biofuels, have partnered and are now actually building a modular, decentralised fast-pyrolysis plant that will convert wood residues into bio-oil. The 200 tonne per day plant will be located in Guelph, Ontario.

The idea behind the concept can be found in other companies and is easy to understand: make the plants modular, so you can bring the plant to the biomass source, instead of bringing the biomass to the plant (earlier post).

Biomass residues from agriculture (such as straw, stems, cobs) and forestry (wood chips, bark, sawdust) are bulky. This means you would waste a lot of energy in gathering and transporting them over long distances to a centralised plant. By making the conversion plant smaller and by locating it near the feedstock, you can densify the residues into a substance with a much higher energy density, in this case, bio-oil (pyrolysis oil). This raw fuel contains 12 times more energy than the bulky biomass, which allows you to transport it over much larger distances (to a centralised refinery).

The whole philosophy of fabrication and construction is modular to minimize on-site activities and allow for the rapid deployment of plants. We have used advanced modeling and fabrication methods to achieve this flexibility. BioOil plants will be quickly deployed given their modular nature and will have the advantage of being located right where the biomass sources are. With an energy density 12 times greater than an original wood residue, it means the BioOil can be transported economically over very large distances. Larry Herman, President of Evolution Biofuels
The modular plant consists of eight modules that are transported in and assembled on site in a relatively quick way. During this assembly phase, biomass operations are already underway at the site. It is estimated that 3,000 tonnes of clean recycled wood has been received and that about 15,000 tonnes of feedstock will be on site in readiness for the start-up early next year. "
