2.0 SYSTEM DESCRIPTION
2.1 System Overview
This section introduces the Totalflow

Model NGC8206 Series Natural Gas
Chromatograph (NGC). The NGC is designed to continually analyze natural gas
streams, on-site, determine composition, calorific value and store the analysis
information. It is designed for natural gas streams, 800 to 1500 Btu/scf (29.8 to
55.9 Mega joules/meter
3
) with less than 100 PPM H2S.
The unit is a fully functional gas chromatograph for pipeline quality natural gas and
is designed to analyze natural gas streams dry of both hydrocarbon liquids and
water. The unit can collect and retain analysis information for one to four
independent sample streams. Applicable installations include: Transmission,
Distribution, Custody Transfer with Metrology quality results, Production, Gas
Gathering and End User Gas Markets.
2.1.1 Framework
Based on ABB Totalflow XSeries technology, the NGC features a common
platform that combines the expandable framework of the XSeries equipment with
the capabilities of a remote gas chromatograph. This expandability allows the
NGC to run other applications such as AGA-3 and AGA-7, while simultaneously
doing stream analysis. This new platform is designed for operation on Windows
CE Real Time Operating System.
2.1.2 Calibration
Once installed on the meter run, the unit can immediately calculate the calorific
value of natural gas. The user can utilize their own calibration blend to adjust the
unit to their company’s standards or take advantage of various automatic
operational features by using the recommended calibration gas.
2.1.3 Typical Installation
This compact unit requires minimal installation time and is fully configured and
calibrated at the factory. A typical single stream pipeline installation includes a
sample probe, optional sample conditioning module, carrier and calibration gas
(see Figure 2-1
). A multiple stream pipeline installation includes an installation
where sample probes may be connected to the NGC (see Figure 2-2).
