Abstract

This study proposed a new CO2 injection system that recovers cold energy in ship-based carbon capture and storage (CCS) chain. The new system used Rankine cycle to recover CO2 cold energy wasted by heating process of CO2 in conventional systems. The study compared the conventional system to the new CO2 injection system in terms of power efficiency. Proper operating conditions including pressure and temperature were defined in accordance with the environmental conditions of the target region. Process simulation was conducted for the comparison of the efficiency of the processes.
