Energy-efficient design and optimization of boil-off gas (BOG) re-liquefaction process for liquefied natural gas (LNG)-fuelled ship

Energy, 2018
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.

Boil off gas (BOG) management in Spanish liquid natural gas (LNG) terminals

Applied Energy, 2010
Abstract Spain is a country with six LNG terminals in operation and three more scheduled for 2011. At the same time an increasing number of LNG tanks are under construction to compensate the Spanish lack of underground storage. A method for evaluating the daily boil off generated is presented in this paper.

Dynamic optimization of the Boil-Off Gas (BOG) fluctuations at an LNG receiving terminal

Journal of Natural Gas Science and Engineering, 2016
Abstract 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.

Automated process design and integration of precooling for energy-efficient BOG (boil-off gas) liquefaction processes

Applied Thermal Engineering, 2020
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.

Minimizing power consumption of boil off gas (BOG) recondensation process by power generation using cold energy in liquefied natural gas (LNG) regasification process

Journal of Cleaner Production, 2019
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.
