Abstract As emission regulation for marine vessels has become strict since 2016, a new emission control method is required. This paper proposes using the H₂O₂ solution in a wet scrubber for SOx and NOx removal for a conventional large marine vessel that uses a low-speed two-stroke diesel engine and a heavy fuel oil, and aims to evaluate the economic feasibility of this approach compared with other methods. Measurement data for the exhaust gas of the engine are incorporated in a process simulation based on physical properties and kinetics that relate H₂O₂ with emission materials. H₂O₂ consumption rate is determined to be 757.38 and 10.37 kg/h, depending on sailing in an emission control area or not. The parameters for techno-economic analysis are based on capital cost, operating cost, sailing information, and fuel cost in January 2018. The net present value of the proposed method is calculated to be 3.26% higher than other methods, and the proposed method is more economical than other methods when the sailing ratio in the emission control area is less than 75.98%. Based on these results, the proposed method can be utilized as an alternative emission control method for a marine vessel that considers retrofitting to satisfy strict emission regulations.

大型船舶湿式洗涤器使用H2O2溶液的模拟与经济性评价

摘要 2016年以来，随着船舶排放法规的严格化，需要一种新的排放控制方法。本文提出在使用低速二冲程柴油机和重油的常规大型船舶的湿式洗涤器中使用 H2O2 溶液去除 SOx 和 NOx，并旨在评估该方法的经济可行性用其他方法。发动机废气的测量数据被纳入基于 H2O2 与排放材料相关的物理特性和动力学的过程模拟中。H₂O₂ 消耗率确定为 757.38 和 10.37 kg/h，具体取决于航行是否在排放控制区。技术经济分析的参数基于 2018 年 1 月的资本成本、运营成本、航行信息和燃料成本。经计算，该方法的净现值比其他方法高3.26%，当排放控制区的航行率小于75.98%时，该方法比其他方法更经济。基于这些结果，所提出的方法可以用作考虑改装以满足严格排放法规的船舶的替代排放控制方法。
