Max Gas Pipeline Velocity
We don't normally measure biogas water content, but you are correct, it is important. The gas starts is journey from the headspace of the digester to the boiler, engine or gas store at digester temperature 37 -56 degrees C typically. As it has been stripped out of the water phase it is...- DrSludge

Max Gas Pipeline Velocity
Davefitz, Thank you for the complement. I am aware of some old 'digestibility' tests for the feedstock for anaerobic digesters, these emerged from the sewage industry in the UK and you might find a British Standard for the assessment of digestibility. The whole concept of measuring efficiency...- DrSludge

Max Gas Pipeline Velocity
I have built a few of these - lets have a look! [The gas and pipework characteristics are - Biogas - 60% CH4, 40% CO2, traces of NOX, SOX & HCL] OK - the gas analysis is impossible. The CH4 and CO2 are OK for a normally operating digester. But it is An-aerobic and without air there is no...- DrSludge
