Method for reliquefying a BOG stream derived from a storage tank for liquefied gas, corresponding system and ship
By extracting liquid from the liquefied gas storage tank and mixing it with the BOG stream, then evaporating and compressing it to condense, the problem of excessively high concentrations of volatile components in the BOG stream is solved, achieving more efficient reliquefaction and fuel gas utilization.

Abstract
本发明涉及一种用于再液化从用于液化气的储存罐（T）中导出的BOG流（B）的方法（100），所述方法具有如下步骤：a1）从储存罐（T）的液相中提取液体（F1）；a2）使液体（F1）蒸发，使得产生蒸发的液体（F2）；b）将蒸发的液体（F2）导入到BOG流（B）中，以便产生混合BOG流（BM）；c）将混合BOG流（BM）压缩到预设的压缩最终压力，使得产生压缩的混合BOG流（BMv）；d）使压缩的混合BOG流（BMv）冷凝，使得产生冷凝的、压缩的混合BOG流（BMvk），尤其借助冷凝器（46）冷凝。
