THEORETICAL SUBSTANTIATION OF METHOD OF DELIVERY LIQUEFIED NATURAL GAS

Statement of the problem. Development of scientific bases of calculation and design of autonomous gas supply systems on the basis of liquefied natural gas (LNG) is an urgent scientific and technical task that takes into account the variability of the determining factors and characteristics of the modern gas supply systems. This requires a comprehensive solution of a number of problems, the main ones are a method for the optimal functioning of the autonomous gas supply systems; development of a method for determining the optimal location of the LNG plant; development of methods of calculation of key parameters of natural gas in the transportation scheme and the use of LNG; technical-economic substantiation of expediency of application of the developed technical solutions in the field of autonomous gas supply, remote from the gas network. Results and conclusions The result of the development is to improve the efficiency and safety of the method of transporting liquefied natural gas using a new design of a transport tank, the essential novelty of which consists in the presence of an additional membrane due to the expansion of geography of deliveries of natural gas in the liquid and gaseous states and further the use of cold by the regasification of LNG, minimizing some of the drawbacks of known methods of liquefying and transporting gas. A numerical algorithm and computer implementation were also developed for technical and economic assessment of the main parameters of the developed scheme of the autonomous supply of gas to consumers remote from gas pipeline network natural gas-based alternative energy source.
