신규 일체형 IFV를 기반으로 한 LNG 동력 선박 냉 에너지 활용 시스템{A LNG-powered ship cold energy utilization system based on a new integrated IFV}LNG-powered ship cold energy utilization system based on a new integrated IFV

본 발명은 LNG 냉 에너지 활용 분야에 관한 것이고, 특히 신규 일체형 IFV를 기반으로 한 LNG 냉 에너지 활용 시스템에 관한 것이다.The present invention relates to the field of LNG cold energy utilization, and more particularly, to an LNG cold energy utilization system based on a novel integrated IFV.

LNG는 높은 발열량과 낮은 연소 오염의 특성을 지닌 고품질 에너지원이다. LNG 터미널의 주요 기능은 원양 수송선이 수송해온 LNG를 받아 저장하고 기화시켜 기체 상태의 천연 가스(NG) 제품을 얻고, 천연 가스 파이프라인 네트워크를 통해 도시 주민 및/또는 산업 사용자에게 공급하는 것이다.LNG is a high-quality energy source with high calorific value and low combustion pollution. The main function of the LNG terminal is to receive, store, and vaporize LNG transported by ocean carriers to obtain gaseous natural gas (NG) products and supply them to city residents and/or industrial users via a network of natural gas pipelines.

LNG는 약 -162 ℃의 저온에서 액체 상태로 존재하는 천연 가스로 기화 과정에 대량의 열원이 필요하다. 일반적으로 LNG 터미널의 기화 설비에는 주로 오픈랙 해수 일체형 IFV(ORV), 중간 매체 해수 일체형 IFV(IFV) 및 수중 연소식 일체형 IFV(SCV)가 있다. LNG 터미널은 바다 근처에 건설되고 해수는 천연 열원이며 일반적으로 기화를 위해 해수를 사용하여 가열한다.LNG is a natural gas that exists in a liquid state at a low temperature of about -162 ℃, and a large amount of heat source is required for the vaporization process. In general, gasification facilities at LNG terminals mainly include open rack seawater integrated IFV (ORV), intermediate medium seawater integrated IFV (IFV), and underwater combustion type integrated IFV (SCV). LNG terminals are built near the sea and seawater is a natural heat source and is usually heated using seawater for vaporization.

선박 동력 장치에 대한 배출 요구가 높아짐에 따라, 운송 선박들은 동력 장치의 원료로 기존의 디젤유 또는 중유 대신 액화 천연 가스(LNG)를 사용하는 것이 불가피한 추세가 되었다. LNG는 기화 과정에서 약 800 kJ/kg의 냉 에너지를 방출하는데 이를 사용하지 않을 경우 대량의 냉 에너지 낭비가 초래될 뿐만 아니라 항로 주변 해역 환경에 일정한 영향을 미친다. LNG 동력 선박의 냉방 요구에 맞는 냉 에너지 활용 시스템을 설계하면, 에너지 활용 효율을 높일 수 있을 뿐만 아니라 압축 냉동 사이클에서 소비되는 전력도 절약할 수 있는데 이는 현재 LNG 활용 기술에서의 최전선 문제 중 하나이다.As the emission requirements for ship power units increase, it has become an inevitable trend for transport ships to use liquefied natural gas (LNG) as a raw material for power units instead of conventional diesel or heavy oil. LNG emits about 800 kJ/kg of cooling energy during the gasification process, and if it is not used, not only a large amount of cooling energy is wasted, but also has a certain effect on the environment around sea routes. Designing a cooling energy utilization system that meets the cooling needs of LNG-powered ships not only increases energy utilization efficiency, but also saves power consumed in the compression refrigeration cycle, which is one of the front-line issues in current LNG utilization technology.

현재 LNG 냉 에너지 활용 시스템은 주로 엑서지 효율을 지표로 사용하고, 냉방, 해수 담수화 등 방식으로 활용하고 있다. “온도 일치, 계단식 활용” 원칙에 따라, LNG 냉 에너지 활용 방안은 일반적으로 다단계 냉방 또는 발전 순환을 사용한다. 단일 단계 시스템에 비해, 다단계 냉 에너지 활용 시스템은 비록 엑서지 효율이 높기는 하지만 시스템 크기가 크고 설비가 복잡하다는 단점도 있다. 기존의 일체형 IFV는 기능이 단일하기에, LNG 냉 에너지를 충분히 활용할 수 있는 동시에 냉 에너지 활용 시스템의 LNG일체형 IFV를 단순화하면서 시스템의 소형화와 경제성을 효과적으로 향상시키는 것은 설비 배치 공간이 제한된 선박에서 특히 중요하다.Currently, LNG cooling energy utilization systems mainly use exergy efficiency as an index, and are used in cooling and seawater desalination methods. In accordance with the “temperature matching, cascading” principle, LNG cooling energy utilization schemes generally use multi-stage cooling or power generation cycles. Compared to the single-stage system, the multi-stage cooling energy utilization system has disadvantages in that the system size is large and the equipment is complex, although the exergy efficiency is high. Since the existing all-in-one IFV has a single function, it is especially important for ships with limited installation space to fully utilize LNG cold energy while simplifying the LNG-integrated IFV of the cold energy utilization system and effectively improving the system's miniaturization and economic feasibility. do.
