Compressing home made biogas Answered
Hi I'm working on a project where we are using an anaerobic digester along with a series of gas scrubbers that yields biogas containing roughly 80% methane (ch4) and 20% oxygen.
I know that this proportion of methane is well above the upper explosive limit of methane (about 15% methane by volume) but the presence of that much oxygen makes me nervous.
Am I going to have trouble compressing this gas mixture without blowing a new hole in my head?
I am planning on compressing the purified biogas to about 20psi at between 60-80 degrees farenheight and in a respectably blast proof gas container.
