船舶造成的空气污染主要来自使用重质燃油发电。虽然这些燃料是经济的，但它们产生大量的污染物排放。为了科普国际海事组织的新排放法规，可以考虑两种方法，一种是使用柴油或船用柴油并采取废气减排措施，另一种是使用液化天然气（LNG）等替代燃料。本研究的目的是从环境和经济的角度对这两种方法进行比较。作为一个案例研究，中速滚装船在红海地区的运行进行了调查。结果表明，在使用海水洗涤的情况下，选择性催化还原法的特定环境效益为减少NOx排放量90%，成本效益为873.5 $/吨，SOx排放量98%，成本效益为3115 $/吨。另一方面，从环境和经济的角度来看，LNG似乎是最佳的建议解决方案。NOx、SOx和CO2排放量分别减少约77.6%、92.5%和14.5%，成本效益分别为1486 $/吨、4084 $/吨和160.8 $/吨。
Air pollution from ships mainly comes from using heavy fuel oils for power generation. Although, these fuels are economical, they produce significant amounts of pollutant emissions. Two methods can be considered to cope with the International Maritime Organization's new emission regulations, either by using diesel fuel or marine gas oil with exhaust gas reduction measures, or by using alternative fuels like Liquefied Natural Gas (LNG). The aim of the current research is to compare between these two methods from environmental and economic points of view. As a case study, medium speed RO-RO cargo vessel operating in the Red Sea area has been investigated. Results show specific environmental benefits of selective catalytic reduction method for reducing NOx emissions by 90% with cost effectiveness of 873.5 $/ton and SOx emissions by 98% with 3115 $/ton in case of using seawater scrubbing. On the other hand, LNG appears the optimum proposed solution from environmental and economic points of view. It reduces NOx, SOx and CO2 emissions by about 77.6%, 92.5% and 14.5% with cost effectiveness of 1486 $/ton, 4084 $/ton and 160.8 $/ton, respectively.
