Optimization of UA of heat exchangers and BOG compressor exit pressure of LNG boil-off gas reliquefaction system using exergy analysis

IOP Conference Series: Materials Science and Engineering, 2015
Boil-off gas (BOG) generation and its handling are important issues in Liquefied natural gas (LNG) value chain because of economic, environment and safety reasons. Several variants of reliquefaction systems of BOG have been proposed by researchers. Thermodynamic analyses help to configure them and size their components for improving performance.

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.

The Role of Fe(II) Minerals in Carbon Stabilization in Coastal and Estuarine Anoxic Environments

Global Biogeochemical Cycles, Volume 40, Issue 1, January 2026.
Abstract Fe(III) (oxyhydr)oxides are well‐known for their role in organic carbon (OC) stabilization in terrestrial soils. Coastal and estuarine soils typically act as iron sinks and receive a high input of OC. However, tidal submersion induces anoxic and reducing conditions that favor the microbial reductive dissolution of Fe(III) (oxyhydr)oxides ...

Conceptual Design of a Metal Hydride System for the Recovery of Gaseous Hydrogen Boil-Off Losses from Liquid Hydrogen Tanks

Engineering Proceedings
Liquid hydrogen (LH2) is a promising energy carrier to decrease the climate impact of aviation. However, the inevitable formation of hydrogen boil-off gas (BOG) is a main drawback of LH2. As the venting of BOG reduces the overall efficiency and implies a

Design and Analysis for Cryogenic Liquid and High‐Pressure Compressed Gaseous Hydrogen Storage Vessels: A Review

International Journal of Energy Research, Volume 2026, Issue 1, 2026.
Cryogenic liquid hydrogen (LH2) and high‐pressure compressed gaseous hydrogen (CGH2) vessels are the core technologies for large‐scale hydrogen storage. This review systematically examines their design challenges and failure mechanisms under extreme cryogenic and high‐pressure conditions. For LH2 vessels, recent advances in thermal insulation, boil‐off

Boil-off gas formation inside large scale liquefied natural gas (LNG) tank based on specific parameters [PDF]

, 2012
Liquefied Natural Gas (LNG) fleets are coasting with various condition and behavior. These variable leads to different type of LNG fleets build every year with unavoidable generated Boil-off Gas (BOG).

Catchment Controls on the Use of Dissolved Organic Nutrients by River Phytoplankton in the United Kingdom

Freshwater Biology, Volume 70, Issue 12, December 2025.
ABSTRACT Dissolved organic matter (DOM) affects the structure and function of aquatic ecosystems and can supply nitrogen and phosphorus to meet the stoichiometric needs of biota. Anthropogenic alteration of the nature and rates of DOM inputs to freshwaters may be increasing the risk of eutrophication, but most of our understanding of DOM use in ...

Sensitivity of LH2 Aircraft Refueling to Process Parameters

Engineering Proceedings
A preliminary analysis of aircraft refueling using liquid hydrogen (LH2) for a future short–medium-range aircraft is presented. The focus is on how selected refueling parameters influence pressure buildup and the release of boil-off gas (BOG), in order ...

A Novel Boil-Off Gas Re-Liquefaction Using a Spray Recondenser for Liquefied Natural-Gas Bunkering Operations

Energies, 2016
This study presents the design of a novel boil-off gas (BOG) re-liquefaction technology using a BOG recondenser system. The BOG recondenser system targets the liquefied natural gas (LNG) bunkering operation, in which the BOG phase transition occurs in a ...

Boreal Rivers as Sources of Terpenoid Emissions

Global Change Biology, Volume 31, Issue 10, October 2025.
Boreal rivers are a significant source of natural airborne chemicals called terpenoids, similar to those released by terrestrial ecosystems. We found these rivers emit a variety of terpenoids, with emissions varying by season and river type. Our findings suggest that rivers should be included when calculating global emissions of these compounds ...
