Model HGC303 - Heat Value Gas Chromatograph
ISO calculation
Description of normalization method
Model HGC303 has four kinds of normalization methods for ISO calculation.
These are Standard normalization, Methane normalization, Helium (variable)
normalization and Helium (constant) normalization. You can select one type of
normalization.
1 Standard normalization method
This method is same as for GPA calculation. Refer to GPA calculation.
2 Methane (CH4, PV9) normalization method
This method is same as for GPA calculation. Refer to GPA calculation.
3 Helium (variable) normalization method
Model HGC303 calculates the normalized concentration using total raw and Helium
concentration by following formula.
Helium calculation
Calculate Helium value using CH4 formula.
Condition
Helium calculation
CH4 < A
He = 0
A <= CH4 < B
He = D
×
CH4 + E
B <= CH4 < C
He = F
×
CH4 + G
C <= CH4
He = 0
Parameters (A, B, C, D, E, F, G) for He calculation can be entered.
Default value is following.
A = 83
B = 88
C = 99.6
D = -0.0274
E = 2.4542
F = -0.00358
G = 0.358
then,
Condition
Helium calculation
CH4 < 83
He = 0
83 <= CH4 <88
He = -0.0274
×
CH4 + 2.4542
88 <= CH4 <99.6
He = -0.00358
×
CH4 + 0.358
99.6 <= CH4
He = 0
Total raw calculation
Total raw = sum of raw concentrations (PV1-PV11)
