mol%. The polynomial coefficients are determined in the factory calibration in
which a correction factor (
response factor ) is calculated for each component in
the automatic and manual calibration.
A
basic calibration is carried out during commissioning and after various repair
and service tasks. The response factors derived from this do not change during
running operation and serve for comparison with the current response factors used
for the evaluation. As a result, it can enable recognition of a drift of the measuring
element due to an enrichment of moisture or heavy carbon dioxide. If the deviation
is greater than 10%, an alarm message appears and the column modules must be
heated to gas out. Basic calibration is not permitted during running operation.
In addition to the custody transfer parameters calorific value and standard density,
which were already mentioned, the analytical computer calculates the heating val-
ue, density ratio and Wobbe index, and, optionally, the methane number as a non-
custody-transfer factors from the individual components. The calculation takes
place in accordance with ISO 6976 (except for the methane number).
1.5 Area of applicability
The analytical computer GC 9300 is an essential element of the overall measuring
unit, which analyzes natural gas and biogas and provides the necessary meas-
urement values to determine the energy content and calculate the compression
ability factor. The analytical computer GC 9300 is the controller, or control com-
puter, for the process gas chromatograph PGC 9300 and controls the analysis
process in the measuring element CP 4900. It stores all operating parameters and
is also used for operation. It records and calculates the measurements, enables
display of the measurement results and calculation factors and stores and trans-
mits this data.
The PGC9300_ME_manual_en_06 (and the English manual) describes the differ-
ent types that are used in different areas. The PGC 9301 is designed for use in
"normal" natural gas. It works with 2 column modules. The PGC 9302 is designed
for use in biogas. It works with 2 column modules (A and C). The PGC 9303 al-
lows the determination of further gas components in "normal" natural gas. It works
with 3 column modules (A, B and C). The PGC 9304 allows the determination of
further gas components in "normal" natural gas. It works with 3 column modules
(A, B and C), whereby argon is used as carrier gas in column C. The PGC 9305
complies with the PGC 9301. For this PGC there will be a separate approval ac-
cording to Russian regulations, the GOST. The differences are described in more
detail in the Russian manual.
The permissible environmental temperatures, current and voltage values for safe
operation are specified in
