摘要：Reliquefaction technologies are being currently applied on board liquefied natural gas (LNG) carriers on the basis of economic criteria and energy efficiency.A variety of reliquefaction techniques have been developed so far during the last decade.Nevertheless,technology enhancement continues being a research area of interest.In this article the different technologies applied to the reliquefaction of the boil-off gas (BOG) on LNG carriers have been described,analysed and discussed,contributing to highlight the process and operation characteristics as well as selection plant criteria.Finally,a comparison of the different reliquefaction plants,considering their capacities and efficiencies as well as other technical data of interest has been carried out.
