DESIGN AND OPTIMIZATION OF A COLD ENERGY AND WASTE HEAT UTILIZATION SYSTEM FOR LNG-POWERED SHIPS WITH POST-COMBUSTION CARBON CAPTURE

ABSTRACT
The introduction of dual-carbon targets has accelerated liquified natural gas (LNG) fuel adoption on vessels and driven the advancement of carbon capture technologies. This study’s aim is a 37000-deadweight tonnage LNG dual-fuel pow¬ered ship, for which chemical absorption carbon capture is applied, utilizing flue gas and LNG to supply the process’s heat and cold energy. Then a system with efficient utilization of energy and carbon capture for the LNG dual-fuel ship is designed, coupling the waste heat onboard with transcritical CO2 and ORC on the principle of energy cascade utilization. The system is simulated using Aspen HYSYS and the exergy analysis is carried out for this system. Then the working fluid is optimized for the system. After that, through the genetic algorithm, the system’s operating parameters are further optimized. Additionally, the system’s economic analysis is also performed. It is shown that the scheme’s exergy efficiency reaches 39.98%, and the expected cost-recovery cycle is 4.75 years.
