Description

부유식 수소생산플랜트{FLOATING PLANT FOR PRODUCING HYDROGEN}Floating hydrogen production plant {FLOATING PLANT FOR PRODUCING HYDROGEN}

본 발명은 부유식 수소생산플랜트에 관한 것이다.The present invention relates to a floating hydrogen production plant.

FPSO(Floating, Production, Storage and Off-loading)를 포함하는 부유식 해양플랜트는 해양에서 천연가스를 생산, 저장 및 출하할 수 있다. 예컨대 해양 가스정(Gas Well)에서 채굴된 천연가스(NG, Natural Gas)에 함유된 수은, 산성가스, 수분은 FPSO의 전처리 공정을 거쳐 제거된다. 이후, 에탄, 프로판, 부탄 등 탄화수소를 분리하는 공정과, 천연가스를 액화시키는 공정 등을 거치게 되고, 생산물은 선체부의 저장탱크에 저장될 수 있다.Floating offshore plants, including FPSOs (Floating, Production, Storage and Off-loading), can produce, store and ship natural gas at sea. For example, mercury, acid gas, and moisture contained in natural gas (NG, Natural Gas) mined from an offshore gas well are removed through a pretreatment process of FPSO. Thereafter, a process of separating hydrocarbons such as ethane, propane, and butane, and a process of liquefying natural gas are performed, and the product may be stored in a storage tank of the hull.

한편, 수소 에너지는 공해가 없는 청정에너지로서 그 실용화 범위가 확대되고 있다. 이러한 수소 생산을 위해 사용되는 종래의 스팀 개질법은 천연가스와 같은 탄화수소 물질을 스팀(수증기)과 개질반응시켜 수소를 추출하는 방법이다. 천연가스는 수소 비율이 높은 메탄(Methane)을 다량 함유하고 있으므로 스팀 개질에 많이 사용되고 있다. On the other hand, hydrogen energy is a clean energy without pollution, and its practical application range is expanding. A conventional steam reforming method used for hydrogen production is a method of extracting hydrogen by reforming a hydrocarbon material such as natural gas with steam (steam). Natural gas is widely used for steam reforming because it contains a large amount of methane with a high hydrogen ratio.
