This paper summarises Aspen HYSYS software-based estimates for natural gas liquefaction technology in harsh Arctic environment. Driven by these findings, a dedicated process technology plant was proposed, along with its mass balance and seasonal energy and material input profiles. The most applicable technology was chosen: a LNG plant using initial cooling by propane and the main process with mixed coolants C3MR Split MR. As new liquefaction plants under design in Russia are mainly located in Arctic regions, the authors point to key climate-related liquefaction aspects: smaller propane consumption and lower process equipment loads in colder months which benefits operating costs. In addition, the paper highlights the key LNG requirements in different consumer countries.
