The invention provides a ship LNG-CO2 storage system based on LNG cold energy utilization, which comprises at least two LNG-CO2 storage tanks, a heat exchanger, an LNG combustion application device, a cold and heat management device, a carbon capture device and a gas compressor, wherein one of the at least two LNG-CO2 storage tanks is a reserved empty tank; a liquid LNG inlet and a liquid carbon dioxide outlet are formed in one side of the heat exchanger; a liquid LNG outlet and a gaseous carbon dioxide inlet are formed in the other side of the heat exchanger; all the LNG-CO2 shared tank bodies are connected with the liquid carbon dioxide outlet of the heat exchanger through a pipeline with a valve; and meanwhile, the pipeline is additionally provided with a branch opening with a valve and is connected with the liquid LNG inlet of the heat exchanger. According to the ship LNG-CO2 storage system, the LNG fuel and the carbon capture technology are adopted at the same time, so that the long-term emission reduction requirement of the International Maritime Organization (IMO) can be met and greatly exceeded; and the economical efficiency can be further improved only by adding another shared tank body on the basis of the quantity of the originally required shared tank bodies of the LNG fuel.
本发明提供了一种基于LNG冷能利用的船舶LNG‑CO2储存系统,包括至少两个LNG‑CO2储罐、热交换器、LNG燃烧应用装置、冷热管理装置、碳捕捉装置和气体压缩机,至少两个所述LNG‑CO2储罐中的一个为预留空罐,在所述热交换器一侧设有液态LNG进口和液态二氧化碳出口,另一侧设有液态LNG出口和气态二氧化碳进口,所述所有LNG‑CO2共用罐体通过带阀门的管道与热交换器的液态二氧化碳出口连接,同时管道另有带阀门分口与热交换器的液态LNG进口连接。本发明的船用LNG‑CO2储存系统,同时采用LNG燃料和碳捕捉技术,能够满足并大大超过国际海事组织(IMO)的长期减排要求;在LNG燃料原有需求共用罐体的数量上,只需要再增加一个共用罐体就可以进一步提高了经济性。
