A floating marine structure is disclosed. In the floating marine structure according to the present invention, the nitrogen oxide contained in the exhaust gas of the waste heat recovery boiler of the power generation unit is removed from the selective catalytic reduction reactor, and the reduction catalyst reactor receives ammonia stored in the ammonia tank, Is reduced by nitrogen and water. And, the ammonia in the ammonia tank must be in a liquid state so that a large amount of ammonia can be stored in the ammonia tank. At this time, since the ammonia in the ammonia tank is kept in a liquid state by using the cold heat of LNG (Liquefied Natural Gas) supplied from the LNG tank to the regeneration unit, a separate heat source for maintaining the ammonia in the ammonia tank in a liquid state ). Therefore, the cost may be reduced. |
