Description of the work
The work in this project is subdivided into three activities:
- Standardisation of the existing Guideline into a Standard for measurement
of tars in biomass producer gases;
- Co-ordination of R&D activities
- Dissemination of the results.
Standardisation
In the first activity, standardisation is performed in a Task Force (number
CEN/TF/143) installed directly under the European Committee for Standardisation
(Comité Européen de Normalisation, CEN). This Task Force has
been applied for at CEN in the previous EU project and will be installed
at the start of the current (new) project. The activities of this Task Force
are twofold:
- Communicate with CEN on progress of standardisation, following the CEN
rules and procedures, document versions of the Standard (including formal
enquiry stage and formal vote stage) and plan plus organise Meetings of the
Task Force including the Technical Experts. Activities include holding the
Secretary and the Chair of the CEN Task Force.
- (b) Ensure technical input to the Task Force from Technical Experts. They
bring in their expertise on tar measurement and use of the Guideline and
define the specifications the Standard has to fulfil. This Group of Technical
Experts discusses existing data on the draft Standard and takes action to
ensure collection of data that are still missing. In particular, data on
accuracy and reproducibility of the draft Standard are essential in the process
of Standardisation.
Co-ordination of R&D activities
&D on the short – term is still required as data on accuracy and reproducibility
of the Guideline method are necessary in order to achieve the Standard Status.
The R&D will comprise mainly the following two routes:
- Round Robin tests of gas chromatographic and gravimetric methods, where
synthetic and real tar samples will be sent out for analysis in different
laboratories.
- Parallel testing, where different laboratories will carry out simultaneous
tar measurements to find out whether the measurement method and measuring
equipment result in comparable numbers.
In addition, also other interesting research activities (e.g. comparison of
the Standard method with alternative methods, testing the Standard at low
tar concentrations) will be stimulated and co-ordinated in the framework of
the project. With this project covering only the co-ordination cost, the actual
R&D will have to be covered by funding from other sources.
Dissemination
In the second activity, the results from this project will be disseminated
to ensure widespread acquaintance with the Standard. Dissemination is aimed
at the companies, institutes and universities working in the field of biomass
gasification. Dissemination will be performed by means of an Internet site,
by using Internet mailing lists/discussion groups and by means of papers
and presentations at Biomass conferences.
