How to calculate the BOG composition in LNG receiving stations
Thread Content
Help: How can the composition of BOG generated in LNG receiving stations be determined? Is it the gaseous composition in equilibrium with the liquid phase? Thank you!
Theoretically, knowing the components of LNG and using the pressure in the storage tanks at the receiving station allows one to determine the gas-phase components; however, it is better to collect gas samples for chromatographic analysis in order to obtain accurate values. For components with high vapor pressures (i.e., those that are volatile), their concentration in the gas phase is higher than that in the liquid phase
Hello, does “theoretically knowing the LNG components and then determining the gas-phase components based on the pressure in the receiving station’s storage tanks” refer to the gas-phase composition in equilibrium with the liquid phase? Thank you!
