Gross Calorific Value (GCV) – Definition and Pronunciation
What is GCV?
GCV (Gross Calorific Value) is the heat produced by the complete combustion of a unit volume of gas in oxygen, including the heat which would be recovered by condensing the water vapor made. Also known as Gross Heating Value, Higher Calorific Value (HCV) or Higher Heating Value (HHV).
Examples of GCV
This error could be avoided by calculating the LNG density and GCV of the actual LNG composition in the cargo tanks instead of the composition determined in the terminal’s pipelines before the ageing.
From “Ship-to-ship LNG transfer operations”.
The gross calorific value (GCV) of gas used in international LNG trading corresponds to the quantity of heat produced by complete combustion in air of a unit of volume or moss of the gas, at a constant standard absolute pressure and a constant standard condensation temperature of the water formed during the combustion.
From “Measurement and calculation of cargo on gas carriers”.
The LNG industry should conform to a standard reference condition for the calculation of GCV because the usage of different reference conditions, and the associated misunderstanding, for both LNG and displaced gas can have financial consequences for the buyer or seller of LNG.
From “Recommended methods for calculating LNG”.
