WebWhat is boil-off-gas? LPG, Liquid Ethylene, LNG tankers are designed to carry natural gas in liquid form at a low-temperature of – 40°C, – 104°C, – 163°C, close to the vaporization temperature. Despite tank insulation designed to limit the admission of external heat, even a small amount of it will cause slight evaporation of the cargo. . This natural evaporation, … WebThe lower the pressure of a gas above a liquid, the lower the temperature at which the liquid will boil. As a liquid is heated, its vapor pressure increases until the vapor pressure …

During LNG storing and transporting, heat from surrounding will cause LNG temperature to rise. The rise of temperature will lead to boil-off gas (BOG) generation. Boil-off gas produced in storage tank should be remove to maintain tank pressure at safe level. BOG can be handled by several methods. WebApr 11, 2024 · At ultra-low LNG temperatures (−160 °C), the pipelines should be precooled by LNG boil-off gas (−120 °C) before normal operation to avoid instantaneous LNG gasification and sharp pipe contraction. In the present study, a transient mathematical model was developed for the precooling process in a subsea multilayered LNG pipeline. city of st. john\u0027s nl bylaws
