Experimental study on solubility of lubricating oils in a supercritical methane gas

International Journal of Naval Architecture and Ocean Engineering, 2022
In a Boil-off Gas (BOG) compressor, there could be a carryover phenomenon of lubricants oil which flows with a solvent gas. To protect process system downstream of the compressor, it is necessary to select low solubility lubricants at supercritical state.

A comparative study on energy efficiency of the maritime supply chains for liquefied hydrogen, ammonia, methanol and natural gas

Carbon Capture Science & Technology, 2022
To cope with climate change, emerging fuels- hydrogen, ammonia and methanol- have been proposed as promising energy carriers that will replace part of the liquefied natural gas (LNG) in future maritime scenarios.

Simulation Model of Regenerative LNG Refrigeration System for Re-Liquification of BOG

Energies, 2020
Boil-off gas (BOG) disposal in liquefied natural gas (LNG) tankers has long been considered inevitable owing to the constant vaporization of the LNG in the storage tanks, but results in energy waste and environmental pollution.

Boil-Off Rate Behavior in a Double-Shell Vacuum-Insulated Cryogenic Storage Tank with Multilayer Insulation

Aerospace
Cryogenic storage systems require precise management of boil-off gas (BOG) to prevent pressure buildup caused by external heat ingress. This study investigates sloshing-induced heat transfer and BOG generation in a double-shell vacuum-insulated cryogenic

Optimal Shape and Boil-Off Gas Generation of Fuel Tank for LNG Fueled Tugboat

한국해양공학회지, 2020
This paper proposes the optimal shape of an LNG fuel tank with a lattice pressure vessel (LPV) design for a tugboat. The LPV is a Type C tank with a design philosophy of “design by analysis,” which facilitates greater variability of shape compared with ...

LNG storage tank evaporation influence factor analysis [PDF]

International Journal of Fluid Engineering
The static evaporation of liquefied natural gas (LNG) is a key factor influencing the safety of LNG storage tanks, since it leads to boil-off gas (BOG) generation and pressure rise inside the tank.

Comparative cost assessment of sustainable energy carriers produced from natural gas accounting for boil-off gas and social cost of carbon

Energy Reports, 2020
As a result of particular locations of large-scale energy producers and increases in energy demand, transporting energy has become one of the key challenges of energy supply. For a long-distance ocean transportation, transfer of energy carriers via ocean

Conceptual Design of Metal Hydride Cartridges with Systematic Alloy Selection and Sizing Guidelines for Boil-Off-Gas Recovery from Liquid Hydrogen

Aerospace
Hydrogen has huge potential for sustainable future industries, but the formation of hydrogen boil-off gas (BOG) is a main drawback of liquid hydrogen (LH2) applications as BOG venting raises safety issues and leads to significant hydrogen loss.

Biological Flora of Britain and Ireland: Geranium sylvaticum*

Journal of Ecology, Volume 114, Issue 2, February 2026.
Geranium sylvaticum is a perennial forb of upland grasslands, woodlands and riverbanks in northern Britain, with scattered native occurrences also in Wales, central England and Northern Ireland. It has an extensive native range in Europe and Asia. The species is gynodioecious, with individual plants typically female or hermaphrodite.
