摘要
过去几年来，液化天然气（LNG）蒸发气再液化技术发展迅速。这种技术在跨洋液化天然气贸易中特别有用，已发展成为世界能源贸易的热门领域。而船上有几个限制条件。减少能耗、提高效率和降低成本是 BOG 再液化过程中的关键因素。本综述全面回顾了近期在设计和优化 BOG 再液化工艺方面取得的进展。其中包括对现有 BOG 再液化技术的详细分析和比较，并特别讨论了两种类型的再液化工艺：动态和稳态。此外，本综述还探讨了改进这两种再液化技术的不同视角和方向。最后，介绍了液化天然气运输船 BOG 再液化工艺面临的挑战，以及应对这些挑战的未来方向。
Review of the design and optimization of BOG re-liquefaction process for LNG carriers
Over the past few years, liquefied natural gas (LNG) evaporated gas re-liquefaction technology has rapidly developed. This technology is particularly useful in trans-oceanic LNG trade, which has grown to be a hot sector in the world’s energy trade. And there are several limitations on board. Reducing energy consumption, improving efficiency, and lowering costs are crucial factors in the BOG re-liquefaction process. This review provides a comprehensive review of the recent advancements in the design and optimization of BOG re-liquefaction processes. It includes a detailed analysis and comparison of existing BOG re-liquefaction technologies, and specifically discusses two types of re-liquefaction processes: dynamic and steady-state. Furthermore, this review examines different perspectives and directions for improving these two re-liquefaction technologies. Finally, the challenges faced by the BOG re-liquefaction process for LNG carriers are presented, along with future directions for addressing these challenges.
