Description

후처리장치를 가진 드릴쉽{DRILLSHIP HAVING SCR SYSTEM}DRILLSHIP HAVING SCR SYSTEM}

본 발명은 후처리장치를 가진 드릴쉽에 관한 것으로, 보다 상세하게는 드릴쉽의 배기시스템 측에 SCR장치를 설치하여 배출가스에 대한 배출규제를 충족할 수 있는 후처리장치를 가진 드릴쉽에 관한 것이다. The present invention relates to a drillship having a post-treatment device, and more particularly, to a drillship having a post-treatment device capable of satisfying emission regulations for exhaust gas by installing an SCR device on the exhaust system side of the drillship. will be.

드릴쉽 등과 같은 해양 시추선에는 추진, 시추작업 등을 위한 발전기 엔진이 설치되고, 이러한 엔진에서 생성된 배기가스는 배기시스템을 통해 대기 중으로 배출된다. Offshore drilling vessels, such as drill ships, are provided with generator engines for propulsion, drilling, and the like, and the exhaust gases generated by these engines are discharged into the atmosphere through an exhaust system.

선박에서 배출되는 배기가스 중 질소산화물과 황산화물은 UN (United Nation, 국제 연합)의 산하기관인 IMO(International Maritime Organization, 국제 해사기구)로부터 배출규제를 받고 있는 대표적인 대기 오염물질들이다. 질소 산화물의 경우는 Tier III가 발효되는 시점인 2016년에 2g/kwh이하로 규제하고 있으며 황산화물을 2010년 7월부터 SECA(sulfur Emission Control Area)에서 1%이하로 배출규제 하기로 하였다.Nitrogen oxides and sulfur oxides in ship exhaust gases are representative air pollutants under emission control from the International Maritime Organization (IMO), a subsidiary of the United Nations (United Nations). Nitrogen oxides are regulated to be below 2 g / kwh in 2016, when Tier III takes effect, and sulfur oxides have been regulated to be below 1% in the Sulfur Emission Control Area (SECA) since July 2010.

질소산화물은 NO, NO2, NO3, N2O, N2O3, N2O4, N2O5를 통칭하지만 대부분의 질소산화물은 NO와 NO2이다. 황산화물은 석탄과 석유와 같은 연료에 포함된 황성분이 연소과정에서 산화된 것으로 주로 SO2이다.Nitrogen oxides are commonly referred to as NO, NO 2 , NO 3 , N 2 O, N 2 O 3 , N 2 O 4 , N 2 O 5 , but most of them are NO and NO 2 . Sulfur oxides are mainly SO 2, which is the oxidation of sulfur components in the combustion process such as coal and petroleum.

질소산화물의 발생 기구는 고온 영역에서 공기 중 질소와 산소가 반응하여 생성되는 Thermal NOx, 연료에서 발생되는 탄화수소가 공기 중의 질소와 반응하여 생성되는 Prompt NOx, 연료에 포함된 질소성분이 연소과정에서 산화되어 생성된 Fuel NOx로 구분된다.The nitrogen oxide generating mechanism includes thermal NOx generated by the reaction of nitrogen and oxygen in the air at high temperature region, prompt NOx produced by the reaction of hydrocarbons generated in the fuel with nitrogen in the air, and nitrogen components contained in the fuel are oxidized in the combustion process. It is divided into Fuel NOx generated.

화석연료의 연소반응으로 생성된 질소산화물을 제거하는 공정으로는 SCR (Selective Catalytic Reduction)과 SNCR (Selective Non Catalytic Reduction)이 대표적이다. SCR은 V2O5-TiO2 계 촉매에 질소산화물과 환원제인 암모니아 혹은 우레아를 주입하여 질소산화물을 질소와 물로 변환하여 제거하는 장치이다. Selective Catalytic Reduction (SCR) and Selective Non Catalytic Reduction (SNCR) are typical to remove NOx produced by the combustion reaction of fossil fuel. SCR is a device that injects nitrogen oxide and reducing agent ammonia or urea into V2O5-TiO2 catalyst to convert nitrogen oxide into nitrogen and water and remove it.

하지만, 종래의 드릴쉽은 선미 측에 공간 및 지지구조 등이 충분하지 않아 SCR장치를 설치하기 어려운 단점이 있었다. However, the conventional drill ship has a disadvantage that it is difficult to install the SCR device because there is not enough space and support structure on the stern side.
