The fermentation, which produces methane from manure and other
organic substances, is a very difficult process to control. That
is why basically all plants today run 20-30 % below the optimal
level in order to make sure, that the process doesn’t kill
itself.
Based
on a co-operation with Aalborg University (Esbjerg) it is now
possible to do online control of the bio mass, and by measuring
the VFA give a warning up to 24 hours ahead, that you should
change the composition of your tank.
This makes it a very
profitable investment – The larger production you can allow
yourself by knowing the development of the fermentation will in
most cases give you a pay back in about a year.
The concept has been Tried
at Linkogas Amba, where trials are ongoing.

Bio fuels
The quality of bio fuel is decisive for the acceptance
in the market.
In Europe CEN 14214
and PrEN 15376:2006 must be adhered to, and our
post-dispersive NIR can with at very high degree of
accuracy measure key parameters like for instance
Moisture, Glycerine, FAEE and FAME.
NREL in USA is one
of our more important partners. They have succeeded in
developing a wide range of calibrations needed for the
production and trade with bio diesel and bio ethanol. |
