Exhaust gas purification of ship in diesel oil combustion and future idea

The IMO (International Maritime Organization) is an administrative organization related to ships. It is a specia lized agency of the United Nations established in 1958 to promote intergovernmental cooperation on maritime issues. As of July 2015, 171 countries and 3 regions including Hong Kong are affiliated.(1)(2) In 2016, as a specific environmental me asure for combustion products emitted from ships, it was required to equip mandatory installation of SCR (Selective Cata lytic Reduction) From 2020, ships that do not have desulfurization equipment will be restricted from using substantially i nferior crude oil (C heavy oil). Companies that operate ships are planning to switch to high quality fuel and get over it, bu t the cost of fuel will increase by more than 20%, so urgent measures are required. In this study, we propose environment al load reduction assuming diesel oil.
