ABB NGC8207 Natural gas chromatograph Description

Description

Calculations supported

• Gas compressibility per AGA 8

• Wobbe Index

• Methane Number

• Optional: AGA 10 speed of sound, Hydrocarbon Dew Point

Installation

The NGC8207 is a weatherproof device designed for

installation “on the pipe” near to the sampling point. This

means it is acceptable to mount outside - in a temperature

range of 0°F to 130°F (-18°C to 55°C) [provides reliable

operation for -20°F to 130°F (-29°C to 55°C) with low

temperature option] onto a pipeline with 2" to 12" pipe sizes

or with an optional pole mount configuration. A cold weather

enclosure is also available if ambient conditions are below

either the sampled gas dew point or the operational

specifications of the unit.

Integrated stream switching

The integral stream selector for the NGC8207 allows sampling

up to four (4) different natural gas streams. Up to two of these

sample streams can be designated as the “calibration/

validation sample”.

Operator interface

Functional setup and operation of the NGC8207 is

accomplished by using a graphical user’s interface software

package named PCCU 32 (supplied with each unit) operating

on a laptop PC in a Microsoft® Windows® environment. The

“Windows®” utilities, combined with software designed

specifically for the NGC8207, provide a powerful tool for

operations, diagnostics, and downstream data handling. The

PC can be directly connected to the NGC8207 via an RS-232,

USB, or Ethernet connection, or indirectly by remote telemetry

(phone modem, radio, cell phone, satellite, etc.).

• NGC ¼ VGA display (optional)
