LNG 인수기지 (LNG Regasification & Storage)

전 세계 44개의 LNG 인수기지(재기화)는 Yokogawa의 DCS를 사용합니다.

Advanced Terminal Unit Control (ATUC) and Advanced Gas Send-out Control

Yokogawa의 현장에서 입증된 ATUC (Advanced Terminal Unit Control) 및 첨단 가스 송출 제어기술은 장치관리를 향상시키고 주요 플랜트 자산의 Start-up(스타트업) 및 Shutdown(셧다운) 과정에서 운전자의 의사 결정을 단순화하여 일치하지 않는 운전조건을 방지합니다. 최적화분 부하분산 (Load Sharing)과 같은 EUM (Enhanced Unit Management) 개념을 통해 고객은 공장의 주요 장비의 운영 효율성과 수명을 높일 수 있습니다. ATUC는 운전자가 펌프를 끄는 것과 같은 장애를 예상하여 가스 송출의 안정성을 크게 향상시킵니다. 간단한 연속 피드백 제어가 이러한 장애에도 대응할 수 있지만, 복구에 필요한 시간은 항상 손실을 초래합니다. 오직 Yokogawa 만 ATUC를 제공합니다. ATUC의 VigilantPlant® 라이브러리 및 기타 엔지니어링 템플릿도 역시 이용할 수 있습니다.

Over the past decade, companies have been using unconventional drilling technology to extract gas and liquid from the readily available shale formations in North America. As the industry gains experience, the production rates continue to rise based on better use of technology to locate resources and to decrease the time from exploration to production.


As LNG moves from a niche to a major area of the oil and gas industry, experienced suppliers are required to deliver the technologies that support it. 


July 2010

Martin te Lintelo, Yokogawa Europe B.V., The Netherlands, discusses high level control system design for LNG receiving terminals. As demand for LNG increases worldwide, players face seemingly conflicting challenges. On one hand, they must expand capacity in different regions, make the business and production as agile and adaptive as possible, and improve operational efficiency.


The LNG sector presents challenges for the automation supplier, particularly in the implementation of automation systems for regasification terminals. Yokogawa Europe's business development manager, upstream oil and gas Martin te Lintelo looks at the handling of the potential automation-related problem areas and opportunities.
