Korea Gas Corporation(KOGAS) have constructed a gas flowmeters' calibration facilities at Jungdong Bucheon. The facilities consisting of 6 reference turbine meters can perform calibrations of large capacity natural gas flowmeters up to 9,600 ㎥/h at 95 kPa. This large capacity and high pressure natural gas facilities is traceable to the national standard of gas flow rate (KRISS). In this article the motive of construction and description of design are summarized.

천연가스가 가스전에서부터 사용자에게 전달되는 방법은, 대단위 배관으로 전달하는 PNG (Pipeline Natural Gas) 방식과 액화해서 전달하는 LNG (Liquified Natural Gas) 방식으로 크게 분류된다. LNG 방식으로 천연가스를 이송할 경우, 천연가스를 약 -162 ℃로 액화해야 한다. 천연가스 액화플랜트는 크게 전처리설비, 중질분 분리설비, 액화설비, 그리고 저장설비로 분리되는데, 그중에 액화설비는 공정 형태에 따라, C3MR, Cascade, DMR 등 여러 공정으로 분류된다. 본 논문에서는 액화공정 중 세계적으로 가장 널리 적용된 C3MR공정에 대한 Simulation을 구성하고 액화 용량 변화에 따른 특성에 대한 연구결과를 설명하였다. There are two ways in the transportation methods of the natural gas from the gas wells to the end users: first, the PNG (Pipeline Natural Gas) method delivering the natural gas through the large-scale pipelines, and the second, the LNG (Liquified Natural Gas) method delivering the LNG after the liquefaction process. When using the LNG method to transport the natural gas, it is essential to liquefy the natural gas to -162℃. The natural gas liquefaction plant consists of a pre-processing process, fractionation process, liquefaction process, and storage tank. The natural gas liquefaction processes are classified into several kinds such as C3MR, Cascade, DMR and others. In this study, it is explained that the simulation study of the C3MR process which is applied worldwide and how the characteristics get changed according to train capacity.

The mechanical driver is a driving equipment for compressors that are mojor equipment at LNG plant. So, the selection of the mechanical driver is important because that factor affect CAPEX, OPEX and availability of whole plant. In the past, a gas turbine was only a method for driving compressors and considered for mechanical driver. But, recently, a electric motor is considered because of developing the technology about turbo-machinery. In this study, the process of selection of mechanical driver type is studied which is more suitable equipment among two turbo-machinerys.
