High Content of CO2 in Gas Pipeline
High Content of CO2 in Gas Pipeline
(OP)
Dear all,
I am doing some study on a platform which produces gas. If there is a leak from a gas pipeline (in which the gas is in high content of CO2 (30mol% to 65mol%)), would the gas burn as jet fire? Or it won't burn?
Thanks.
Regards,
SL.

The range of values you've provided is not that far from land-fill gas that runs engine-driven compressors just fine.

The harder I work, the luckier I seem
RE: High Content of CO2 in Gas Pipeline
a) 37% CO2, 49% Methane: estimate 490 BTU/SCF
b) 30% CO2, 16% Methane: estimate 167 BTU/SCF
So, the a) would burn when ignited rather than b). Am I correct to say that?
RE: High Content of CO2 in Gas Pipeline
From the BTU content, the missing 54% on "B" must also be inert. "B" would probably burn, but I would think that the ignition temp would be really hot (100% methane has an autoignition temp around 1,000F) and wouldn't be suprised to see that it had to be exposed to 1,500F for a prolonged period to ignite. I'd be reluctant to try to run 167 BTU gas into an engine.
