ABB NGC8209 Natural gas chromatograph

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.

A single computer controller seamlessly processes all this

data for various outputs. It also handles the stream switching

and the timing for the sample. Incorporating a state-of-the-art

built-in 32 bit digital controller, three electronic carrier

pressure regulators, oven-mounted sensors and advanced

low-noise digital electronics, the NGC 8209 performs with

unparalleled repeatability and sensitivity. The NGC 8209

provides custody transfer/metrology quality Chromatography

for heating value and composition measurement. It provides

the user with a GC that is lower in cost, easier to install and

commission, and less costly to operate.
