The theme of this research is the intermediate fluid vaporizer (IFV) gasification system for an offshore liquefied natural gas floating storage regasification unit (LNG-FSRU). Based on reducing the loss of heat exchange and improve the cold energy utilization, an LNG cold energy utilization system combined with Rankine cycle power generation and desalination is proposed. On this basis, six different schemes of working medium combination are simulated and analyzed, and the optimal scheme of working medium combination is found. The results show that the net output power of the system is 5591 kw, and the system exergy efficiency is 30.38%. The annual economic benefit is CNY 39.4 million.

In this paper, based on the idea of reducing heat exchanger exergy destruction and increasing turbine work, a new three-stage cascade Rankine system and a new four-stage cascade Rankine system is proposed to improve the cold energy utilization rate during liquefied natural gas(LNG) gasification on liquefied natural gas-floating storage and regasification unit. Then compare them with the original cascade Rankine cycle established under the same conditions. The results show that under the condition of 175 t/h LNG flow, the maximum net output power of the new three-stage cascade Rankine cycle system is 4593.31 kW, the exergy efficiency is 20.644%. The maximum net output power of the new four-stage cascade Rankine cycle system is 5013.93 kW, and the exergy efficiency is 22.509%. Compared with the original cascade Rankine cycle system, the maximum net output power of the new three-stage cascade Rankine cycle system and the new four-stage cascade Rankine cycle system is increased by 9.41% and 11.45%, respectively, and the system exergy efficiency is increased by 9.29% and 11.28%, respectively.
