How is LNG sampling done in cylinders?
Answer:
LNG as in Liquid Natural Gas is sampled as a gas, not a liquid just due to it's temp. The sample is collected with enough pressure in the cylinder to provide feed gas to a chromatagraph. The sample is then run through the cromatagraph analyzer and the product analysis given listing the components.
Our current component specs are:
Nitrogen - .5% or less
Methane - 94.89% or more
CO2 - .01% or less
Ethane - 2.0% or less
Propane - .1% or less
