Description

The truck is moved as close to the sample point as is practical.

A flexible sample line is then uncoiled and attached to the probe

in the flowing natural gas pipeline. If the dew point of the gas or

the weather demands it, this flexible tubing must be heated. A

sample of the gas is extracted from the probe in the line, purged

through the flexible line and then transported to the analyzer.

There it is processed for particle removal and phase integrity,

injected onto the chromatographic columns where component

separation occurs. These components are then quantified by

peak integration and concentration is calculated. The other data

of interest is then calculated from these concentrations.

The Portable NGC8209 analyzes each sample utilizing

established chromatographic techniques. The resulting

information consists of mole percent values for the following:

– Air (Contains N2, Ar, CO and O2 but not CO2), C1, CO2, C2,

C3, IC4, NC4, NeoC5, IC5, NC5, C6’s, C7’s, C8’s, C9+

The NGC8209 measures a C9+ (back flushed) peak. Users may

input the results of a comprehensive lab analysis that reflects

the split or ratio of C9 through C12 components. This ratio can

be used in subsequent analyses and energy calculations.
