Sažetak
This paper examines the problem of evaporation of
Liquefied Natural Gas (LNG) occurring at different places in
the LNG supply chain. Evaporation losses in the LNG supply
chain are one of the key factors for LNG safety, technical and
economic assessment. LNG is stored and transported in tanks
as a cryogenic liquid, i.e. as a liquid at a temperature below its
boiling point at near atmospheric pressure. Due to heat entering
the cryogenic tank during storage and transportation, a part of
the LNG in the tank continuously evaporates creating a gas called
Boil-Off Gas (BOG), which changes the quality of LNG over time.
The general methods of handling and utilization of the Boil-Off
Gas at different points in the LNG supply chain are presented.
Attention is given to the issue of LNG energy content transferred
during loading and unloading of LNG tankers, as well as to the
Boil-Off Gas generated by evaporation of the cargo during
maritime transport. The results presented in the paper have been
derived from the scientific research project 250 - 2502209 - 2366
„Management of Ship Power Systems under Fault Conditions
and Failure“ supported by the Ministry of Science, Education and
Sports of the Republic of Croatia.
