NITROGENOUS COMPOUND EMISSION REDUCTION APPARATUS AND OPERATION METHOD IN SHIP

摘要

The present invention relates to an exhaust gas harmful substance reduction apparatus in a ship and an exhaust gas harmful substance reduction operation method and, more specifically, relates to an exhaust gas harmful substance reduction apparatus in a ship and an exhaust gas harmful substance reduction operation method. When a ship sails and operates, in accordance with a sailing section of the ship or an operation section of a marine plant, any one of air or oxygen that is an oxidizer of fuel supplied to an engine is selected to be supplied to the engine. As the supplied oxygen is applied with oxygen generated in a ballast water treatment unit or oxygen generated by gasifying liquid oxygen, a conventional engine is used for a ship or a marine plant, and exhaust gas nitrogen oxide emission control Tier 3 of the engine can be satisfied.
