The heating value depends on the source of gas that is used and the process that is used to liquefy the gas. The range of heating value can span ±10 to 15 percent. A typical value of the higher heating value of LNG is approximately 50 MJ/kg or 21,500 BTU/lb. [2] A typical value of the lower heating value of LNG is 45 MJ/kg or 19,350 BTU/lb.
The gas produced in boil off is traditionally diverted to the boilers and used as a fuel for the vessel. Before this gas is used in the boilers, it must be warmed up to roughly 20 °C by using the gas heaters. The gas is either fed into the boiler by tank pressure or it is increased in pressure by the Low Duty [clarification needed] compressors.
Liquefied natural gas is natural gas that has been liquefied for the purpose of storage or transport. Since transportation of natural gas requires a large network of pipeline that crosses through various terrains and oceans, a huge investment and long term planning are required. Before transport, natural gas is liquefied by pressurization.
Gas is supplied from two world-class gas fields namely, Gorgon field that contains on average 14% of naturally occurring reservoir CO 2, and Jansz-lo field that contains less than 1% CO 2. [3] Reservoir CO 2 is extracted from natural gas as a part of normal gas-processing operations. During the liquefaction process, natural gas is cooled to ...
Liquefied natural gas is the liquefied form of natural gas, which has a much smaller volume than natural gas in its gaseous form.This liquefied condition is used to facilitate the carriage of natural gas over long distances, often by sea, in specialized tanks.
The natural gas that fuels dual fuel engines is carried on ships as a boiling liquid and transported at slightly higher than atmospheric pressure. When tank insulation is penetrated by an influx of heat, it causes the temperature of the liquefied natural gas to rise which allows for vaporization from liquid to gas. When heat penetrates the tank ...
A liquefied natural gas terminal is a facility for managing the import and/or export of liquefied natural gas (LNG). It comprises equipment for loading and unloading of LNG cargo to/from ocean-going tankers , for transfer across the site, liquefaction, re-gasification, processing, storage, pumping, compression, and metering of LNG.

Its first liquefied natural gas (LNG) was delivered in January 1983 (the first cargo dispatched on 29 January 1983). On 1 June 1992, Malaysia LNG Dua Sdn Bhd (MLNG Dua) was incorporated to manage and operate the second LNG plant of three trains with 2.6 Mtpa capacity each. Its first LNG was delivered in May 1995.
