Abstract:
This project aims at the development of an analyser
for the on-line measurement of tar dewpoints in biomass product gases.
The work has been executed according to the project proposal. On basis
of the specifications for the tar dewpoint analyser (TDA), an existing
hydrocarbon dewpoint sensor was modified and a gas conditioning section
was designed for tar dewpoint measurements. Preliminary laboratory tests
with the gas conditioning section and dewpoint sensor were run to investigate
the performance and fouling characteristics of the dewpoint sensor and
the gas conditioning section. The TDA (gas conditioning section sensor)
was tested and validated downstream the laboratory scale BFB gasifier
at ECN. Tar dewpoints between 25°C and 170°C could successfully be measured.
After finishing the tests a pre design for a commercial analyser was
made. Finally, the market for the TDA was identified and segmented in
R&D groups, indirect co-combustion and stand-alone biomass gasification
installations.
