JOR3-CT98-0253 Bio fuel oil - upgrading by hot filtration and novel
physical methods. A supporting action for a demonstration scheme
Objectives
Following overall objectives for the R&D
project have been defined :
- To increase the market value of BFO by improving BFO quality as fuel.
- To improve the utilisation of BFO in power plants and boilers.
The specific technical objectives are :
- To develop hot vapour filtration at process development unit (PDU)
scale to remove solids from BFO The present solid content of 0.5 to 2 wt
% will be reduced to < 0.1 wt%.
- To develop microemulsion technology, which would make it possible to
use BFO and mineral oil mixtures in existing equipment without major
modifications Three emulsions will be manufactured and characterised in
laboratory analysis.
- To maximise organic yield by varying key process parameters
(temperature, residence time) for pyrolysis of three feedstocks (forest
residues pine sawdust, and straw).
- To develop bio fuel oil handling and storage procedures, and to
study the health and safety issues related to industrial use of BFO.
- Four BFO and derivatives will be employed in laboratory scale
equipment to characterise their fundamental combustion behaviour.
- To develop use of BFO in medium scale heating boilers. Performance
and emissions of CO NOx and particulates will be measured for two BFO in
a 200 kW boiler.
- To support the development of a BFO as power plant engine fuel by
generating basic engine performance and emission data.
- To determine the competitiveness of BFO as heating oil in Finland and
Sweden.
Technical Approach
These objectives are
pursued in following tasks :
- Development of hot filtering for pyrolysis oil production.
- Microemulsion production from BFO and mineral oil.
- BFO production in PDU scale.
- Handling and storage of BFO and heath and safety issues related to
BFO.
- Fundamental behaviour of BFO in combustion.
- Medium size boiler tests.
- Engine tests.
- Bio fuel oil markets, biomasss production and pre-treatment.
Some of the experimental equipment employed in the work are :
- - A PDU pyrolyser with a slip-stream hot filter.
- A bench-scale pyrolyser with a hot filter.
- A bench-scale micro-emulsion preparation unit.
- Bench-scale units to study combustion of fuel droplets.
- A 200 kW boiler.
- A single cylinder test engine.
The principal feedstocks to be employed are forest residues, pine
sawdust, and straw.
Expected achievements and exploitation
Expected
achievements include :
- An improved, solids free BFO (production in PDU-scale).
- Production of microemulsions in laboratory scale.
- Performance data on the production of BFO for three fuels.
- Improved understanding of BFO combustion by laboratory experiments.
- Data on boiler emissions.
- Performance and emissions using BFO as engine fuel.
- Strategies for BFO market introductions.
