    Co2 Gas Natural
AI Thread Summary
A user is seeking a real-time device to measure CO2 levels in natural gas, specifically targeting a concentration of about 5% with a resolution of 0.1%. They mention that a gas chromatograph is currently used but is too slow to detect rapid changes in CO2 levels. Recommendations for alternative devices include checking with specific sensor manufacturers. The discussion emphasizes the need for a faster response time in CO2 measurement for natural gas applications. The inquiry highlights the challenges in accurately monitoring gas composition under specific conditions.

Does anyone know of a device that will measure the percentage of CO2 (about 5% and resolution down to 0.1%) in natural gas, in real time, the gas is at approx 40 bar and 30 Deg C.
Thank you

No, we have a gas chromatograph but the response is too slow, I'm trying to catch a rise in CO2 that is faster then the chromatograph will see.
 
Thanks Ivan I'll contact them.
 

Thread 'Query on Isentropic relationships (such as PV^gamma = constant)'

Hi all, I have a question. So from the derivation of the Isentropic process relationship PV^gamma = constant, there is a step dW = PdV, which can only be said for quasi-equilibrium (or reversible) processes. As such I believe PV^gamma = constant (and the family of equations) should not be applicable to just adiabatic processes? Ie, it should be applicable only for adiabatic + reversible = isentropic processes? However, I've seen couple of online notes/books, and...

Thread 'Dry sump pump issue'

I have an engine that uses a dry sump oiling system. The oil collection pan has three AN fittings to use for scavenging. Two of the fittings are approximately on the same level, the third is about 1/2 to 3/4 inch higher than the other two. The system ran for years with no problem using a three stage pump (one pressure and two scavenge stages). The two scavenge stages were connected at times to any two of the three AN fittings on the tank. Recently I tried an upgrade to a four stage pump...
