[Digestion] Measuring the gases produced

[frank]

Hi Methane producers,

Are there standard procedures for measuring the gas make up coming from 
the digester? I am thinking the most will be CH4 and CO2 with some 
ammonia and nitrogen.  I am thinking the CO2 can be scrubbed out using 
NaOH and titrated or determined by the gas reduction. Perhaps the CH4 
can be by difference? or measured using a SnO2 cell?

We have set up a pilot plant for experimenting with different feedstock 
and are ready for testing the trapped gas.



Any suggestions is appreciated.
Thanks
Frank
