Özet

© 2021 Elsevier LtdThis study investigates the effects of hydraulic design parameters of separation columns on the effectiveness of the solvent-based carbon capture and storage (CCS) systems and performs the cost analyses of CCS systems for different ships. The CCS and power systems of ships are simulated by using process modeling with Aspen HYSYS. A very large crude carrier (VLCC) tanker and three different sizes of liquefied natural gas (LNG) carriers (Q-Max, Q-Flex, and conventional LNG carrier) are considered. The study also employs different carbon control methods such as speed reduction and LNG usage. These methods are compared in terms of their CO2 emission reduction effectiveness and costs. Comparisons between the speed reduction, LNG usage, and the CCS system show that the speed reduction is the best cost-oriented and easiest solution for ships with low freight values like crude oil tankers. However, for ships with high speed and freight values like Q-Max and Q-Flex LNG carriers, it is shown that the CCS is more cost-effective than other compared CO2 control methods. The results show that the CCS system is a promising and feasible method for reducing CO2 emissions of ships.
