The NGC 8209, the C9+natural gas chromatograph performs on-site natural gas

analysis and heating value computation using an extended analysis.

Benefits

On-line chromatograph techniques are used to provide N2

through C6+ data while a third column train is used to

separate the C6+ fraction. The NGC 8209 utilizes the modular

and scaleable XSeries software framework to integrate data

from a third analysis train into the standard C6+ analysis of

the Natural Gas. The extra chromatographic information is

provided as NC6’s, NC7’s, NC8’s and C9+ to provide this

“extended analysis”. Heating value (CV), Wobbe, Relative

Density (SG) and other calculations are performed using the

combined analysis data in a similar manner to the NGC 8206.

Hydrocarbon Dew Point (HCDP) and Speed of Sound (SOS)

calculations are available options.
