Boil off gas (BOG) management in Spanish liquid natural gas (LNG) terminals
Applied Energy, 2010Abstract 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, 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 The boil-off gas (BOG) compressor is one of the most critical pieces of equipment in the handling of boil-off gas from liquefied natural gas (LNG). It ensures the safety of the transportation and receiving systems of LNG. This study used a three-dimensional finite element model to investigate the heat transfer process in the cylinder of a ...

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 Energy efficiency of the conventional boil-off gas re-liquefaction process in the LNG-fueled ships, which is based on a single expander cycle, can be improved with structural modifications, such as a dual expander cycle. Herein, a structural optimization framework concept is proposed to systematically screen a wide range of configurational ...

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 The increased size of Liquefied Natural Gas (LNG) plants worldwide has led to an increase in boil-off gas (BOG) flows. The BOG can be either liquefied again to LNG or compressed to higher pressure levels for use as fuel gas.
