Jan 2, 2025 · Boil-off Gas (BOG) is an essential yet often overlooked component in the maritime industry. As liquefied natural gas (LNG) gains traction in global shipping, understanding and managing BOG becomes paramount. The evaporation of LNG during transport and storage can lead to significant safety and efficiency concerns.

Nov 16, 2020 · This natural evaporation, known as boil-off-gas (BOG) is unavoidable and has to be removed from the tanks in order to maintain the cargo tank pressure or structure integrity. Other than heat leak, there are other scenarios can lead to BOG generation: Vaporized vapor due to barometric pressure decrease & ambient temperature increase.

Boil-off gas (BOG) is the vapor that is generated as a result of the natural evaporation of a cryogenic liquid, such as liquefied natural gas (LNG), during storage or transport.

Jul 17, 2019 · New limitations on sulphur emissions will require ship operators to consider alternative fuels. As a result, the use of forced LNG boil-off gas (BOG) is likely to increase.

Nov 1, 2023 · BOG recovery systems are designed to absorb the maximum amount of BOG during liquefied natural gas (LNG) loading to ships (loading mode). Additional BOG is generated during the loading process (loading mode).

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, known as boil-off is unavoidable and has to be removed from the tanks in order to maintain the cargo tank pressure.

An onboard reliquefaction system that recovers boil-off gas in LNG carriers and returns it to the cargo tank s. The BOG, at about -143°C and atmospheric pressure, is taken from the cargo tanks and passed through a compressor, where its pressure is raised to 4.5 bar and temperature to …

Apr 12, 2024 · With its increased focus on environmentally-friendly designs and operations, the global LNG carrier fleet has accepted boil-off gas management systems as the de-facto standard for today’s LNG carrier designs.

Apr 15, 2024 · With its increased focus on environmentally friendly designs and operations, the global LNG carrier fleet has accepted boil-off gas management systems as the de facto standard for today’s LNG carrier designs.

To ensure the eficiency of Elliott BOG compressors, we’ve developed and tested a new type of AIGV system to accurately and eficiently control mass flow and pressure at extremely low temperatures (-300° F).
