Dynamic optimization of the Boil-Off Gas (BOG) fluctuations at an LNG receiving terminal
Journal of Natural Gas Science and Engineering, 2016Abstract Heat leakage and mechanical energy input by equipment evaporate Liquefied Nature Gas (LNG) in LNG receiving terminals into Boil-Off Gas (BOG), which must be compressed and liquefied by sub-cooled LNG in a recondenser. During ship unloading, there are sharp fluctuations in BOG waste resources, causing economic loss.

Abstract Liquefied natural gas (LNG) fuelled shipping systems adopts the boil-off gas (BOG) re-liquefaction process to maintain the pressure of storage tank and to minimize methane loss. However, most of previous studies on on-board BOG re-liquefaction process were made for large-scale applications of LNG carriers.

Abstract During the process of storage and transportation of liquefied natural gas (LNG), boil off gas (BOG) is generated. The presence of BOG causes the rise of pressure of the storage tank, and makes the LNG receiving terminal have a large safety hazard, which needs to be condensed and recovered.

Abstract As awareness on air pollution in marine environment increases, transition of ship fuel to natural gas has been recognized as a practical solution for emission minimization. It is realized with LNG-fueled ship, whose implementation in practice demands cost-effective and energy-efficient re-liquefaction of BOG.

Abstract In this paper, a numerical model considering phase change and external heat leakage is established to study the thermodynamic and hydrodynamic of a type C LNG tank under sinusoidal sloshing excitation. The volume of fluid (VOF) method, coupled with the mesh motion treatment, is adopted to predict the movement of the vapor-liquid interface ...
