Abstract

This article is dedicated to the detection and calculation of unavoidable gas losses due to the measuring devices and technological processes of auto-gasification pressure stations (CNGs), which are conditioned by the productivity of CNGs. The productivity of CNG stations operating in the territory of RA differs according to their daily charging capabilities, i.e. according to the number of existing gas pressure stations. The need of analysis and development of such methodology stems from new approaches in flow measurements, which are of high importance in ensuring uniformity of measurements in gas transportation and distribution systems. The accurate determination of CH4 emissions is of high necessity in the scope of environmental management systems, which already function according to the international requirements prescribed by ISO 14001 as well. In the territory of the Republic of Armenia the development of such a methodology result from the implementation of Article 150 of the Government Decision No. 1101-N of August 28, 2008 "On approving the technical regulation of the minimum requirements for the construction and operation of gas filling stations" of the Republic of Armenia.
