Fuel Oil Equivalents (FOE)
The following are the relative conversion equations.
FOE Volume to Standard Gas Volume
The conversion of fuel oil equivalent (FOE) volume to standard gas volume requires the heat content of a volume of fuel oil constant and the heat content of the material.
Where:
VSN = Gas volume at standard or normal conditions
V = Volume in fuel oil equivalent (FOE) volume units
BtuToFOEVol = Global constant of heating value per volume of fuel oil. The value is from the Global Factors element, SF_GlobalFactors.
FOEConv = Fuel oil equivalent heating value of material per gas volume
Standard Gas Volume to FOE Volume
The conversion of standard gas volume to FOE volume requires the heat content of a volume of fuel oil constant and the heat content of the material.
Where:
VSN = Gas volume at standard or normal conditions
V = Volume in fuel oil equivalent volume units
BtuToFOEVol = Global constant of heating value per volume of fuel oil. The value is from the Global Factors element, SF_GlobalFactors.
FOEConv = Fuel oil equivalent heating value of material per gas volume
FOE Mass to Mass
The conversion of FOE volume to mass requires the heat content of a mass of fuel oil constant and the heat content of the material.
Where:
mass = Mass of gas
M = Mass in fuel oil equivalent mass units
BtuToFOEMass = Global constant of heating value per mass of fuel oil. The value is from the Global Factors element, SF_GlobalFactors.
FOEConv = Fuel oil equivalent heating value of material per gas mass
Mass to FOE Mass
The conversion of mass to FOE mass requires the heat content of a mass of fuel oil constant and the heat content of the material.
Where:
mass = Mass of gas
M = Mass in fuel oil equivalent mass units
BtuToFOEMass = Global constant of heating value per mass of fuel oil. The value is from the Global Factors element, SF_GlobalFactors.
FOEConv = Fuel oil equivalent heating value of material per gas mass
