摘要
为有效遏制温室效益带来的全球气温上升,提出一种以K2CO3+PZ作为吸收剂的船舶碳捕集系统,研究在5RT-Flex50DF发动机柴油模式和燃气模式下,不同工况和不同捕集效率时船舶碳捕集系统的经济性.结果表明:船舶碳捕集成本与发动机工况呈负相关,与捕集率呈正相关,燃气模式下利用LNG冷能可有效降低CO2压缩液化成本;在固定捕集效率下,优化碳捕集系统参数后,无需引入额外能源对系统进行供能,船舶碳捕集成本可降低至103 $/t,此时系统可变运营成本大幅度降低.研究成果可为船舶碳捕集技术应用提供参考.
Abstract
In order to effectively mitigate global temperature rise caused by greenhouse effect,an onboard carbon capture system using K2CO3+PZ as absorbent is proposed.The economy of onboard carbon capture system under different working conditions and different capture efficiency is studied in diesel and gas mode of 5RT-Flex50DF engine.The results show that onboard carbon capture cost is negatively correlated with engine working conditions,and positively correlated with capture rate.Using LNG cold energy in gas mode can effectively reduce the cost of CO2 compression and liquefaction.After fixing the capture efficiency and optimizing the parameters of the carbon capture system,there is no need to introduce additional energy to power the system,and the cost of onboard carbon capture can be reduced to 103 $/t,which significantly reduces the variable operating cost of the system.The research results can provide references for the application of onboard carbon capture technology.
