More Information
Summary:CO_2 capturing is increased and overall plant efficiency is improved by integrating a natural gas liquefaction system, a hydrogen production system, and a power generation system. Mainly methane end-flash is sent to the hydrogen production system which produces hydrogen and CO_2. CO_2 is either captured or beneficially used. At least a portion of the hydrogen produced is used to supply fuel to a gas turbine during power generation, which in turn provides power to a refrigeration compressor in the natural gas liquefaction system in the form of mechanical work or electricity. 천연 가스 액화 시스템, 수소 생산 시스템 및 동력 생성 시스템을 통합하여 CO2 포집을 증가시키고 전체 플랜트 효율성을 개선한다. 주로 메탄 엔드플래시는 수소와 CO2를 생성하는 수소 생산 시스템으로 전송된다. CO2는 포집되거나 유익하게 사용될 수 있다. 생성된 수소의 적어도 일부는 동력 생성시 가스 터빈에 연료를 공급하는 데 사용되며, 이는 차례로 기계적 일 또는 전기의 형태로 천연 가스 액화 시스템의 냉동 압축기에 동력을 제공한다.
