◊ Wobbe

◊ Methane-number

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. 

BENEFITS

The NGC 8209, the C9+ Natural Gas Chromatograph

performs on-site natural gas analysis and heating

value computation using an extended analysis.

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.

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.

Hydrocarbon Dew Point

Installation

The NGC8206 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

Description

The NGC8206 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+

Using process chromatographic techniques, the columns are

back flushed so that the NGC8206 measures a C6+ peak. Users

may input the results of a comprehensive lab analysis that

reflects the split or ratio of C6 through C10 components. This

ratio can be used in subsequent analysis and energy

calculations. Calculated values include:

• Gas compressibility per AGA 8

• Real Relative Density (Specific Gravity)

• Btu/CV Value

• GPM (gallons of liquid per thousand cubic feet)

• Wobbe Index

• Methane Number

• Optional calculations can include: AGA 10 speed of sound
