To understand I am building a methane digester system, and am going to store the gas at 24.13Bar (350psi) in 3 * 100 pound lp tanks 0.2M^3 (7.05cubic feet)

My feed stock will be at .69Bar (10 psi) ruffely and cool at say 10c (50F), so far my calculations tell me I'll have a 10.7 compression ratio and temp lift will be near 204C (400F) does this sound right to you all>
