Based on this, a mathematical model for calculating the boil-off gas (BOG) amount was .Włodek [32] compared the boil-off gas (BOG) generation with three types of LNG-light, heavy, and nitrogen-containing LNG (2. The energy and costs required to reliquefy the . If boil-off gas leaks out, it can significantly increase the proportion of methane and ethane in the air . LNG tanker s are designed to carry natural gas in liquid form at a temperature of – 163°C, close to the vaporization temperature. BOG conditions for the case study are listed in Table 1.
These sources include heat leaks from ambient air around the storage tank, heat ingress due to the dissipation of pumping power inside the tanks, heat leaks from pipelines, flash vapor generated by liquid rundown and displaced vapor from the tank due to liquid filling (known as the piston .
