Development of Recommendations for the Creation of Liquefied Natural Gas Infrastructure

Abstract

Statement of the problem. As a rule, when choosing a method of transporting natural gas to various ca-tegories of consumers, several options are considered depending on the mutual distance between the source and the consumer — the construction of a gas pipeline or the creation of an infrastructure for li-quefied gases. The competitiveness of liquefied natural gas (LNG) in comparison with natural gas is proposed to be determined within the framework of model gas supply schemes for different ranges of alternative energy supply systems. Results. The results of the calculation according to the developed algorithm based on the Clark-Wright method allow us to conclude on the least expensive layout option for automotive cryogenic tanks and cryogenic storage facilities for consumers, determine the number of working hours per month for truck tanks, and also determine the optimal number of cryogenic tanks to deliver the required volume LNG and the number of cryogenic storage tanks at consumers. Conclusions. The proposed economic and mathematical model can be used to substantiate the competitiveness of the use of natural and liquefied natural gases to meet the various needs of consumers. The proposed mathematical calculation model makes it possible to identify the efficiency of each of the energy carriers, as well as to identify the main criteria for choosing the most efficient energy carrier for specific conditions of use.
