Description
Summary:Liquefied natural gas (LNG) is an economical form of storage and transportation of natural gas. The demand for LNG is increasing steadily and the infrastructure for its supply is developing as the LNG market expands. This paper reviews the LNG production technologies in terms of their production capacity. The main LNG production volumes (85–90%) are concentrated at large-capacity plants located in coastal areas or at floating plants. In current conditions, new strategies are needed for implementing LNG projects based on medium- and small-capacity plants that can better meet new market demand. Through construction of several lines, they can achieve the production volumes of large-capacity projects. Medium- and small-capacity LNG plants mean modularity, factory assembly, shorter plant construction time, and possibility of development of marginal wells and alternative sources of methane-containing gas. The main advantage of LNG is the possibility of recovering up to 40% of the energy spent on liquefaction during the regasification process. Natural gas contains small amounts of heavy inert gases, which are enriched during the liquefaction process. The development of a technology for extracting Kr and Xe from natural gas is a promising area of further research.
