Design and thermodynamic Analysis of Integrated Cold Energy Management System for FLNG Ships
In order to reduce the energy loss during transport of FLNG ships,a FLNG ship energy comprehensive utilization system was designed,to collect the cold energy discharged during LNG re-vaporization and store it in the storage tank.When the ship is in the peak period of electricity load,the stored cold energy can be used to generate electricity and drive the system com-ponents to realize the BOG reliquefaction process.According to the structural characteristics of the system,a system thermody-namic model was constructed to carry out the exergic analysis.The numerical results showed that the system could achieve 66.4%exergic efficiency,of which 46.2%exergy loss came from heat exchanger and 38.4%from compressor.
