【摘要】:LNG浮式接收再氣化裝置(Floating Storage Regasification Unit,FSRU)具有審批流程簡化、建設周期短、投資小、供氣速度快等優(yōu)勢。基于此,對其關鍵系統(tǒng)的技術可獲得性、設備可靠性、建造周期進行了分析,并且從可靠性、安全性、投資成本、運營成本、環(huán)境影響及建造周期等方面對浮式接收再氣化方案進行了梳理。結果表明:卸料臂使用壽命長、運營成本低,建議浮式接收再氣化裝置采用卸料臂進行旁靠卸載;再氣化系統(tǒng)可采用丙烷或乙二醇溶液作為中間介質進行換熱,根據(jù)裝置系泊港口的環(huán)境條件、環(huán)保要求、船體蒸汽系統(tǒng)負荷來確定使用。與FSRU相比,浮式接收裝置(Floating Storage Unit,FSU)的再氣化模塊布置靈活,可以進行冷能利用,運營成本降低,可靠性與安全性更高,經濟性更佳,是浮式接收再氣化裝置的發(fā)展新趨勢。
[Abstract]:LNG floating Storage Regeneration Unit (FSRU) has the advantages of simplified approval process, short construction period, small investment and fast gas supply. Based on this, the technical availability, equipment reliability, construction cycle of the key system are analyzed, and the reliability, security, investment cost, operation cost are analyzed. The floating receiving and regasification scheme is combed in terms of environmental impact and construction cycle. The results show that the unloading arm has long service life and low operating cost. It is suggested that the floating receiving and regasification device should be unloaded by the discharge arm, and the propane or ethylene glycol solution can be used as the intermediate medium for heat transfer in the regasification system. According to the environmental conditions of mooring port, environmental protection requirements, ship steam system load to determine the use. Compared with FSRU, the regasification module of Floating Storage Unit (FSU) has the advantages of flexible layout, cold energy utilization, lower operating cost, higher reliability and safety, and better economy. It is a new trend of development of floating receiving and regasification unit.
