The invention relates to the technical field of LNG (liquefied natural gas) transport ships and floating type storage and regasification devices (FSRU), in particular to an FSRU cargo control and regasification comprehensive gas treatment system which comprises a liquefied natural gas storage cabin, an evaporator and a regasification module. The liquefied natural gas storage cabin is communicated with a boil-off gas pipeline, and the boil-off gas pipeline is respectively communicated with a pressure and temperature reduction station, a high-pressure compressor, a light-load compressor 1 and a light-load compressor 2; the gas treatment system provided by the invention not only can meet the requirement of efficiently and safely treating the boil-off gas and avoid environmental pollution and energy waste, but also provides reference for different requirements of different projects, and proper gas treatment equipment and system can be selected for subsequent actual projects according to different gasification capacities, local environmental protection requirements and the like, so that the gas treatment efficiency is improved. The cargo boil-off gas is efficiently and safely treated, the availability and flexibility of an FSRU project are enhanced, and effective operation of a whole ship gas treatment system is guaranteed.
本发明涉及LNG运输船和浮式储存和再气化装置(FSRU)技术领域,尤其为FSRU货物控制和再气化综合气体处理系统,包括液化天然气储存舱、蒸发器和再气化模块,所述液化天然气储存舱的液化天然气管道与蒸发器相互连通,所述液化天然气储存舱与蒸发气管道相互连通,所述蒸发气管道分别连通设置有减压减温站、高压压缩机、轻载压缩机1和轻载压缩机2;本发明提出的气体处理系统不仅能满足高效安全处理蒸发气的需求,避免环境污染和能源浪费,同时也为不同项目不同要求提供参考和借鉴,后续实际项目可根据气化能力不同、当地环保要求等选择合适的气体处理设备和系统,对货物蒸发气进行高效安全处理,增强FSRU项目的可用性和灵活性,保证全船气体处理系统的有效运行。
