Sustainable boil-off gas utilization in liquefied natural gas production: Economic and environmental benefits

Journal of Cleaner Production, 2021
Boil-off gas (BOG) causes negative environmental impacts related to gas streams flaring in the liquefied natural gas (LNG) industry. This study addresses the resources and energy management and discusses the economic and environmental benefits of ...

Numerical study of the boil-off gas (BOG) generation characteristics in a type C independent liquefied natural gas (LNG) tank under sloshing excitation

Energy, 2021
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 ...

Energy-efficient process design and optimization of dual-expansion systems for BOG (Boil-off gas) Re-liquefaction process in LNG-fueled ship

Energy, 2020
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 ...

Design Considerations for High Pressure Boil-Off Gas (BOG) Centrifugal Compressors With Synchronous Motor Drives in LNG Liquefaction Plants

Volume 9: Oil and Gas Applications; Supercritical CO2 Power Cycles; Wind Energy, 2019
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.

Performance and economic evaluation of nitrogen-based indirect LNG boil-off gas (BOG) re-liquefaction process integrated with an absorption refrigeration cycle

In this study, a nitrogen-based LNG BOG re-liquefaction process was established as the baseline case, and a process integrating an NH3/H2O single-effect absorption refrigeration cycle (ARC) driven by shipboard waste heat as an auxiliary cooling source was proposed.
