The paper describes a new method for numerical monitoring of discrepancies in natural gas supply to consumers, who receive gas from gas distribution loops. This method serves to resolve the vital problem of commercial natural gas accounting under the conditions of deficient field measurements of gas supply volumes. Numerical monitoring makes it possible to obtain computational estimates of actual gas deliveries over given time spans and to estimate their difference from corresponding values reported by gas consumers. Such estimation is performed using a computational fluid dynamics simulator of gas flows in the gas distribution system of interest. Numerical monitoring of the discrepancy is based on a statement and numerical solution of identification problem of a physically proved gas dynamics mode of natural gas transmission through specified gas distribution networks. The identified mode parameters should have a minimum discrepancy with field measurements of gas transport at specified reference points of the simulated pipeline network.

The formation of the modern Ukrainian natural gas market is accompanied by profound transformations of the national gas infrastructure: the creation and operation of new market operators, the redistribution of infrastructure facilities, the development and implementation of new requirements for the effective functioning of the entire system. At the same time, this requires from all parties a verified and balances strategy for the optimal implementation of all the obligations that Ukraine has undertaken to fully implement the requirements of the EU Third Energy Package, which aims to create an effective natural gas market based on the principles of free competition, proper consumer protection and security of supply. Despite the fact that the capacity of the Ukrainian gas transmission system and gas storages is one of the largest in Europe, the unbanding process has caused a number of threats in the area of regulatory support for production activities, requiring the consolidation of specialists' efforts to form optimal solutions to the problems that have arisen. In addition, the lengthy process of reforming and reorganizing the Ukrainian gas distribution system has led to a situation where the work of a natural gas distribution operator is facing a risk of imbalance in terms of inefficient standardization of the main areas of operation to meet the EU legislation requirements implemented in Ukraine. Therefore, to develop basic directions for the future work of gas infrastructure operators, it is necessary to take into account the acting capabilities of existing system for transportation, underground storage and gas distribution (taking into account the significant number of standardized indicators defined by the existing normative documents of the former USSR) and in accordance with the trends in the development of the European gas infrastructure introduce economically and technically feasible measures to standardize performance activities. Such works have to be incorporated into integrated research programs, during which regional and international trends are to be taken into account and adapted, the results of which will be the basis for future roadmaps and programs for the development of natural gas supply and distribution systems.

Maintaining the gas temperature and the formation of gas hydrates is one of the main problems in the operation of gas pipelines. Development and implementation of new effective methods for heating the gas during gas reduction will reduce the cost of gas transportation, solve the problem of resource and energy saving in the fuel industry. Study is aimed at increasing the energy efficiency of the natural gas reduction process by using a resonant gas heater to maintain the set temperature at the outlet of the gas distribution station (GDS) and prevent possible hydrate formation and icing of the station equipment. Paper considers the implementation of fireless heating of natural gas and fuel gas savings of heaters due to the introduction of a thermoacoustic reducer, operating on the basis of the Hartmann – Sprenger resonance effect, into the scheme of the reduction unit. By analyzing the existing methods of energy separation and numerical modeling, the effectiveness of the resonant-type energy separation device is substantiated. Modification of the reduction unit by introducing energy separating devices into it will allow general or partial heating of natural gas by its own pressure energy. Developed technology will allow partial (in the future, complete) replacement of heat energy generation at a gas distribution station by burning natural gas.

Gas Heating

Natural gas can be directly used for heating of flats by gas distribution system. Indirectly, heating power plant can disburse natural gas and deliver hot water or steam for heating of flats. Decision of optimal way for gas heating usage is done based on spatial disposal of building, number and size of buildings in settlement, etc. Optimal solution, between gas distribution and district heating system (local or district heating by natural gas), can be done according to methodology (model approach) shown in this paper. According to variety of Serbian settlements (in density, size and layout of buildings) model which has ability to represent their different characteristics is formed. This model could be simple and useful tool for initial decision about energy supply system.
