Application of Boil Off Gas Compressors in LNG Plants
Volume 3B: Oil and Gas Applications; Organic Rankine Cycle Power Systems; Supercritical CO2 Power Cycles; Wind Energy, 2014This paper discusses complexities and challenges of managing boil off gas (BOG) in LNG liquefaction plants. Most publications in the past have focused on regasification terminals and have not addressed the area of liquefaction plants. The paper discusses the generation and management of BOG and the associated networks and machinery to manage it.

Minimizing Boil-Off Losses in Liquefied Natural Gas Transportation
Industrial & Engineering Chemistry Research, 2009Natural gas (NG) is the cleanest fossil fuel, which is most popular and economical after crude oil. Liquefied natural gas (LNG) is the most economical way of transporting NG over long distances. Because of LNG transportation and storage at −163 °C, boil-off losses are an unavoidable reality.

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.

Proper handling of boil-off gas (BOG) significantly affects the operational efficiency as well as the safety of the whole LNG gasification plant. Due to the not well-known inherent dynamics, it has been suspected that the BOG compressors are being operated at too much capacity, unnecessarily consuming too much energy. An empirical model is proposed for

A prototype test of dynamic boil-off gas in liquefied natural gas tank containers
Applied Thermal Engineering, 2020Abstract The safety concern of transporting liquefied natural gas (LNG) by tank container is still an unsolved problem. One of the key issues for LNG tank container transportation is that the dynamic boil-off gas (BOG) generation during the shipping has not been systematically characterized.

A voyage optimization model of LNG carriers considering boil-off gas
OCEANS 2019 MTS/IEEE SEATTLE, 2019A voyage optimization model is proposed to minimize the operating costs of LNGC (Liquefied Natural Gas Carrier). The model is utilized to suggest the RPM and route plan of the vessel based on the amount of boil-off gas generated. Voyage optimization of LNGC is different from that of general cargo ships because of the natural characteristics of its ...

Dynamic Simulation Study for Boil-off Gas Minimization at Liquefied Natural Gas Exporting Terminals
Industrial & Engineering Chemistry Research, 2017The boil-off gas (BOG) generation at LNG (liquefied natural gas) exporting terminals is significant and should be minimized and/or recycled efficiently and effectively. In this work, the study of BOG generation, minimization, and recovery has been performed for a typical LNG plant with C3MR (propane precooled mixed refrigerant) process, storage ...

An efficient pulse tube cryocooler for boil-off gas reliquefaction in liquid natural gas tanks
Applied Energy, 2016Small liquid natural gas (LNG) distribution stations require compact, highly efficient cryocoolers to reliquefy boil-off gas in the LNG tank. This paper describes a pulse tube cryocooler measuring 420mm×690mm×780mm and weighing 180kg. With low input electric power, the relative Carnot efficiency exceeded 20%.

Retrofit design of a boil-off gas handling process in liquefied natural gas receiving terminals
Energy, 2012Abstract Generation of Boil-off gas (BOG) in liquefied natural gas (LNG) receiving terminals considerably affects operating costs and the safety of the facility. For the above reasons, a proper BOG handling process is a major determinant in the design of a LNG receiving terminal.
