Model HGC303 - Heat Value Gas Chromatograph
1) Real dry heating value per unit volume: HV (dry) [BTU/CF]
Real GHV (dry) and Real NHV (dry) are calculated using the following formula.
ex.
where,
GHV
id
= ideal gross heating value per unit volume
(GHV
id
)
i
= ideal gross heating value per unit volume for component
i
xi
= mole fraction for component
i
2) Real saturated (sat) heating value per unit volume: HV (sat) [BTU/CF]
Real GHV (sat), Real NHV (sat) are calculated using the following formula.
ex.
Real GHV (sat)
=
where,
xw
= mole fraction of water
3) Dry heating value per unit mass: HM (dry) [BTU/lbm]
GHM (dry), NHM (dry) are calculated using the following formula.
ex.
GHM (dry)
=
where,
ti
= weight fraction for component
i
(GHM
id
)
i
= ideal gross heating value per unit mass for component
i
4) Compressibility factor Z (dry)
Compressibility factor (dry) is calculated using the following formula.
Z (dry)
=
where,
PB
= Base pressure
bi
= summation factor at 60
