Model HGC303 - Heat Value Gas Chromatograph
Formulas
This section shows formulas for heat value calculations.
1) Compression factor
2) Superior calorific value
3) Inferior calorific value
4) Density
5) Relative density
6) Wobbe Index
1) Compression factor Zmix
Compression factor Zmix = 1 - [sum (xj
×
sqrt (1 - Zj)) + xhelium
×
sqrt(b)helium] ^ 2
where,
xj
= mole fraction for component j
xhelium = mol fraction for Helium
Zj
= compression factor for component j at (t2, p2) (ISO6976 Table2)
sqrt(b)helium = square root of summation factor for Helium at (t2, p2)
(ISO6976 Table 2)
2) Superior calorific value SCV(MJ/m
3
)
Ideal gas superior calorific value, SCV (ideal) = sum (xj
×
Hs0j)
Real gas superior calorific value, SCV (real) = SCV (ideal) / Zmix
where,
xj
= mole fraction for component j
Hsoj = ideal superior calorific value for component j, at (t1/t2) (ISO6976 Table 5)
3) Inferior calorific value ICV(MJ/m
3
)
Ideal gas inferior calorific value, ICV (ideal) = sum (xj
×
Hl0j)
Real gas inferior calorific value, ICV (real) = ICV (ideal) / Zmix
where,
xj
= mole fraction for component j
Hloj = ideal inferior calorific value for component j, at (t1/t2) (ISO6976 Table 5)
