BTG-BTL has plans to build a pyrolysis plant at Hengelo's AkzoNobel site. The letter of intent was signed at the end of September by AkzoNobel Industrial Chemicals, Empyro and BTG Bioliquids. In the new plant wood will be converted to oil. The plant will also deliver steam to AkzoNobel and generate electricity for delivery to the public grid.
Largest pyrolysis plant in Europe
The Empyro plant, owned by the shareholders Tree Power and BTG Bioliquids, will convert 5 metric tons of dry wood into oil, steam and electricity, per hour. This conversion takes place on a commercial scale and uses a technique, owned by BTG Bioliquids. This technique has already proven itself in Malaysia, where a plant uses residual products of a palm oil plant. The new pyrolysis installation will be the largest in Europe and building it will require an investment of approximately 13 million Euros. A substantial part of the investment will be covered by an European subsidy because it is a pilot project. The installation will be built on a piece of land of 1 hectare and will be 20 meters high. Next to the plant a number of smaller buildings will be established for amongst other things the storage of biomass, a steam turbine and tanks for oil. It is expected that the construction can start in the second quarter of 2010. The planning depends primarily on the license procedures and the overall funding of the plant. One year after the start of the construction the plant has to be operational.
Steam for salt production
AkzoNobel rents out the land and also supplies various utilities and possibly supporting staff when the plant operates on a stable level. The steam, which becomes available as a by product of the production of the oil, will also be used by the salt plant. We expect that in future 5% of the steam required for the salt production is supplied by the new installation, which further ‘greens’ the manufacturing process.
