Description

BOG 회수시스템의 모니터링 시스템BOG recovery system monitoring system

By receiving measurement information from the received explosion-proof field device and outputting 3D visualization information to display measurement information based on graph-type 2D visualization information and modeling, the user can perform analysis, but display measurement information Prevent errors due to transmission and reception of all information, filter measurement information for safety monitoring,

벙커링(bunkering)은 벙커유로 알려진 선박 연료유를 저장 및 전송하는 것을 주로 의미한다. 최근에는 액화천연가스(LNG: Liquefied Natural Gas)의 사용이 늘어남에 따라 LNG 연료의 전송 및 공급도 벙커링으로 포함되고 있다.Bunkering mainly means storing and transmitting ship fuel oil known as bunker oil. Recently, as the use of Liquefied Natural Gas (LNG) has increased, the transfer and supply of LNG fuel has also been included as bunkering.
대량의 연료를 해안으로부터 선박까지 전송하기 위해서는 LNG 연료를 바지선이나 다른 컨테이너에 임시적으로 저장한다. 따라서, 연료 공급은 도크 또는 다른 항만 시설로부터 직접 이루어지거나, 바지선 또는 다른 연료 급유선에 의해 운반된 연료를 공급받아 이루어질 수도 있다. In order to transfer large amounts of fuel from shore to ships, LNG fuel is temporarily stored in barges or other containers. Accordingly, the fuel supply may be made directly from a dock or other port facility, or may be provided by receiving fuel carried by a barge or other fuel tanker.
상기의 LNG는 천연가스를 약 -162℃로 냉각해서 액화시킴으로써 얻을 수 있는 무색투명한 액체로서, 천연가스와 비교해 약 1/600 정도의 부피를 갖는다.The LNG is a colorless and transparent liquid obtained by liquefying natural gas by cooling to about -162°C, and has a volume of about 1/600 compared to natural gas.
천연가스의 액화온도는 상압 -163℃의 극저온이므로, LNG는 그 온도가 상압 -163℃ 보다 약간만 높아도 쉽게 증발된다. 따라서, 벙커링을 통해 선박의 LNG 저장탱크로 LNG를 이송할 때에도, 온도와 압력 등의 변화에 따라 다량의 BOG(BOG: Boiled-off gas)가 발생한다.Since the liquefaction temperature of natural gas is an extremely low temperature of -163°C at normal pressure, LNG easily evaporates even if its temperature is slightly higher than -163°C at normal pressure. Therefore, even when transferring LNG to the LNG storage tank of the ship through bunkering, a large amount of BOG (boiled-off gas) is generated according to changes in temperature and pressure.
BOG의 양은 저장 용기 내부의 액위 변동에 따라 그 발생량이 달라지므로 외기온도, 압력변화에 따른 Heat & Mass Balance 예측을 통해 대기 중으로 방출되는 BOG의 손실 량을 최소화 해야 한다.Since the amount of BOG varies depending on the change in the liquid level inside the storage container, it is necessary to minimize the amount of loss of BOG released into the atmosphere by predicting the heat and mass balance according to the change in outside temperature and pressure.
만일, 저장 용기 내에 BOG가 과다하게 되면 이로 인해 용기 내 압력이 상승하면서 용기가 내부 압력을 견딜 수 없어 폭발할 위험이 있으므로, BOG를 배출시켜 액화한 후 다시 저장해야 한다.If the BOG is excessive in the storage container, the pressure in the container rises due to this, and the container cannot withstand the internal pressure, and there is a risk of explosion. Therefore, the BOG must be discharged, liquefied and stored again.
이와 같이, BOG를 배출시켜 액화한 후 다시 저장해야 하기 위해서는 높은 압력과 낮은 온도를 수반해야 하므로 시스템의 안전성이 중요하고, 이를 모니터링할 필요가 있다.As described above, in order to discharge the BOG and liquefy it, it must be accompanied by a high pressure and a low temperature, so the safety of the system is important and it is necessary to monitor it.
상기와 같이, BOG의 회수는 경제적 측면뿐만 아니라 환경적 측면, 그리고 폭발, 화재의 위험성 때문에 높은 기술적 완성도를 요구되기 때문에 발전소 운영 과정에서 발생할 수 있는 위험 예측 및 모니터링을 통해 자산 안전성을 확보해야 한다.As described above, the recovery of BOG requires not only economical aspects but also environmental aspects and high technical completeness due to the risk of explosion and fire, so asset safety must be secured through risk prediction and monitoring that may occur during the operation of the power plant.
종래에는 위험 예측 및 모니터링을 위해 선박으로부터 수신된 계측 데이터를 이용하였으나, 선박으로부터 수신되는 각종 계측 데이터의 경우 해양 환경(즉, 조류, 바람, 파도)에 의해 정확한 데이터를 전달 받기 힘든 경우가 대 부분이며 이러한 문제점으로 인하여 전체 플랫폼에 대한 시스템 노후 대비가 어려웠다.In the past, measurement data received from ships was used for risk prediction and monitoring, but in the case of various measurement data received from ships, it is difficult to receive accurate data due to the marine environment (ie, tide, wind, waves). And due to this problem, it was difficult to prepare for the system aging for the entire platform.
