However, there are lots of restrictions on board and BOG re-liquefaction is an energy-intensive industrial process. Reducing energy … frond palmWebWhen tankers transport liquefied natural gas (LNG), a slight evaporation of the cargo – known as boil-off gas (BOG) – is inevitable. To maintain the right tank pressure, it is essential to remove BOG from the tanks. The conventional method has been to use some BOG as fuel for propulsion, while excessive gas is burnt in a gas combustion unit. frondtech elden ring white screenWebJan 1, 2013 · and Boil-off Gas (BOG) In order to transport natural gas, it is economical to convert it to LNG. The conversion process involves cryogenically cooling the natural gas to -163 °C at atmospheric pressure, at which point the gas condenses to a liquid and is ready for transport. The refrigerated tanks on board the ship ensure the liquid gas remains fronducksWebliquefied natural gas (LNG). Maintaining LNG in its liquid form at low pressure requires extremely low temperatures. Handling boil off gas (BOG) is inherent to the process. During LNG storage and transportation, as surrounding temperatures cause the LNG temperature to slowly rise, the LNG begins to evaporate or “boil.” The frond sourcesWebBOG is conventionally pressurized with compressor and then sent as city gas or fuel for power generation together with LNG gas vaporized by heat exchanger.
