This 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.

本研究调查了分离塔的水力设计参数对溶剂型碳捕集与封存 (CCS) 系统有效性的影响，并对不同船舶的 CCS 系统进行了成本分析。通过使用 Aspen HYSYS 的过程建模来模拟船舶的 CCS 和电力系统。考虑了一艘超大型原油运输船 (VLCC) 油轮和三种不同尺寸的液化天然气 (LNG) 运输船（Q-Max、Q-Flex 和传统 LNG 运输船）。该研究还采用了不同的碳控制方法，例如减速和使用 LNG。比较这些方法的 CO ₂减排效果和成本。减速、LNG使用和CCS系统的比较表明，对于原油油轮等低运价船舶，减速是成本导向的最佳解决方案，也是最简单的解决方案。然而，对于像 Q-Max 和 Q-Flex LNG 运输船这样具有高速和货运价值的船舶，CCS 比其他比较的 CO ₂控制方法更具成本效益。结果表明，CCS系统是减少船舶CO ₂排放的一种有前景且可行的方法。
