Vessel emissions have contributed a great deal to air quality deterioration in China. Hence, the Chinese government has promulgated a series of stringent emission regulations. It is in this context that vessel emission control technology research is in full swing. In particular, during the 13th Five-Year Plan, the air pollution control technology of vessels has greatly improved. Vessel emission control has followed two main governance routes: source emission reduction and aftertreatment technology. Source control focuses on alternative fuels, with two main directions, the development of new fuels and the modification of existing fuels. Moreover, after-treatment technologies have also been developed, including wet desulfurization technology using seawater or alkaline liquids as wet washing liquids and selective catalytic reduction (SCR) for the control of NOx emission. Due to China's increasingly stringent emissions standards and regulations, work on the development of clean alternative fuels and further upgrading the collaborative application of after-treatment technologies to meet the near-zero-emissions requirements of vessels is still necessary.
船舶排放对中国的空气质量恶化有很大的贡献。因此，中国政府颁布了一系列严格的排放法规。正是在这种背景下，船舶排放控制技术的研究正在全面展开。特别是在“十三五”期间，船舶的空气污染控制技术有了很大的提高。船舶排放控制主要有两种治理途径：源头减排和后处理技术。源头控制侧重于替代燃料，主要有两个方向，开发新型燃料和改进现有燃料。此外，还开发了后处理技术，包括使用海水或碱性液体作为湿法洗涤液的湿法脱硫技术和用于控制 NOx 排放的选择性催化还原（SCR）。由于中国日益严格的排放标准和法规，开发清洁替代燃料的工作以及进一步升级后处理技术的协同应用，以满足船舶的近零排放要求仍然是必要的。
