[Digestion] Compressing Biogas into a Tank

[Paul Harris]

G'day Gerry,

Biogas does react with mineral oil (we havd several destroyed
compressors to attest to this!) but synthetic oil is apparently OK.

Methane will not liquify at room temperatures and getting high pressures
is very energy intensive.

Hope this is some help,
HOOROO

We can have a simple and practical way to make better use of this fuel.
