This paper proposes a procedure of calculus of the technological consumption, usefully for the operators of the natural gas distribution systems. It also sets, based on a statistical study, the minimum possible value of the technological consumption for the operators of natural gas distribution in Romania. There are indicated the environmental issues resulting from the technological consumption and the measures to control and reduce it.

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.

Crystalline Hydrates

The existing methods for natural gas dehydration both in fields and at compressor stations cannot always provide standatdized values of natural gas dehydration. The analysis of operation of gas distribution systems shows that dehydration units are improperly placed and are often installed out of condensation and freezing zones. This is due to the lack of consideration of phase transitions impact in gas throttling on its temperature condition. Due to insufficient natural gas dehydration, crystalline hydrates can be formed on wellbores, distribution lines and main gas pipelines and at its reduction, disturbing the operation of the equipment of compressor stations, gas distribution stations, deranging instrumentation and automation. The issues of reliability of gas pipeline systems considering the formation of crystalline hydrate plugs in pipelines have been studied. The analysis of the methods and devices preventing hydrates formation and eliminating existing crystalline hydrate plugs has shown that to provide normalized parameters of the transported gas it is necessary to perform additional water vapor, condensate drops and crystalline hydrate particles removal from natural gas at gas distribution stations during winter months. Currently applied methods used to deal with crystalline hydrate plugs in main gas pipelines require significant expenses and do not effectively ensure the reliability of pipelines operation. An energy-efficient design of an integrated treatment unit which provides an additional natural gas treatment at GDS, increases the reliability of gas pipelines protection against hydrate blockage and improves the efficiency of gas supply systems as a whole have been proposed at the Department of Heat and Gas Supply and Ventilation of the SWSU.
