摘要：This paper aims at the problem of cold energy utilization of LNG floating storage regasification unit (FSRU). A comprehensive LNG-FSRU cold energy utilization scheme was proposed based on ship-shore sharing. Using energy cascade theory and energy conservation theory to design a cold energy cascade utilization system that includes air separation, dry ice making, horizontal two-stage Rankine cycle power generation, seawater desalination, ship refrigerated storage, air conditioning and ice making. Using Aspen HYSYS to carry out system simulation calculation and parameter optimization to determine the optimal program and operating parameters. Establishing the mathematical model of the cold exergy utilization system to analysis cold energy efficiency by using the Peng-Robinson equation calculation method. The analysis results show that the using efficiency of cold exergy reaches 29.57% which proves that the cold utilization system of the floating LNG storage regasification plant is reliability with large economic value.
