Determination of the Optimal LNG Plant Location in the Gas Supply Area Plan

Abstract

Liquefied natural gas (LNG) is rather competitive and can act as an alternative fuel. Zone determination for economically expedient use of this energy resource is a necessary prerequisite for solving an important task - providing consumers with gas fuel. Development of scientific bases of calculation and design of autonomous gas supply systems on the basis of liquefied natural gas 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. The article presents the results of technical and economic studies of gas distribution systems based on liquefied natural gas, proposed a numerical algorithm and its computer implementation to determine the location of the plant for liquefying gas. Conducted calculations and comparative analysis show that LNG-based gas supply systems will provide fuel for consumers located at considerable distance from the source of gas supply (main gas pipeline or gas distribution station).
