Thermodynamic and Economic Analysis of Cargo Boil-Off Gas Re-Liquefaction Systems for Ammonia-Fueled LCO₂ Carriers

Journal of Marine Science and Engineering
In this study, cargo boil-off gas (BOG) re-liquefaction systems for ammonia-fueled liquefied carbon dioxide (LCO2) carriers were analyzed. These systems use cold energy from ammonia to reliquefy the CO2 BOG.

Performance enhancement of marine LNG BOG reliquefaction systems via passive diffuser integration: a thermodynamic and economic assessment

Journal of Engineering and Applied Science
This article presents a novel thermodynamic approach to improve energy efficiency and cost-effectiveness of boil-off gas (BOG) reliquefaction systems on marine carriers. The study investigates the impact of installing six stationary diffusers upstream of

EN Methods for managing the energy efficiency of a reliquefaction plant operating on the reverse brighton cycle of a LNG tanker

Holodilʹnaâ Tehnika i Tehnologiâ
LNG is transported over long sea and ocean distances only by tankers, called LNG carriers, in large on-board tanks at a temperature of -163ºC. Although these tanks are well insulated, some of the LNG evaporates under the external factors influence, and ...

Study of Predictive Control Model for Cooling Process of Mark III LNG Bunker

Polish Maritime Research
When loading liquefied natural gas (LNG) onto a dual-fuel LNG container ship fuelled by LNG, there is a considerable temperature difference between LNG and the fuel tank at room temperature. The current solution is to pre-cool the tank with LNG through a
