Calculate the liquid density of LNG vaporization components
Thread Content
The components of LNG after gasification are shown in the table below. How can the density of liquid LNG be calculated? Volume percentage, molecular weight: Methane – 98.93, 116.04276; Ethane – 0.7753, 0.07; Propane – 0.044, 4.1; Isobutane – 0.0035, 8.12; n-Butane – 0.0025, 8.12; Isopentane – 0.0017, 2.1488; n-Pentane – 0.0017, 2.1488; 2-Methylpentane – 0.0017, 2.1488; 3-Methylhexane – 0.0018, 6.18; n-Hexane – 0.0018, 6.18; Heptane – 0.0011, 100.2; Carbon dioxide – 0.0014, 4.0095; Oxygen – 0.0013; Nitrogen – 0.1782, 8.013. Vaporization rate (m3/ton) at (-162 to 20°C): 1488.83. Relative density of the gas: 0.5577. Gas density (kg/m3): 0.6717
