Abstract

Objective. The purpose of the research is modeling and analysis of technological processes occurring at the transshipment terminal of liquefied natural gas.

Method. The study is based on the methods of thermodynamic analysis, full-scale and computational modeling of processes and objects of refrigeration and cryogenic equipment in order to find optimal solutions in terms of efficiency, reliability and service life of low-temperature installations, machines and apparatus.

Result. The article describes the operation algorithm of an LNG transshipment terminal and proposes a mathematical apparatus for modeling the technological processes occurring in it. Information about the causes of the formation of LNG vapors (Boil-off gas (BOG)) during its transportation and reloading is presented, methods for utilizing excess LNG vapors are considered.

Conclusion. To maintain the cryogenic temperature of the unloading arms, an LNG recirculation line (recirculation pipelines) is provided.
