Estimation of Emissions During Monitoring of Pipelines in the Dynamic Mode of Operation

Abstract

Abstract. To determine and diagnose the emissions from pipelines operating in the dynamic mode, the model is developed in real time, whereby the determination of the oil leakages volume is possible with sufficient accuracy. The stated methods assume the use of computer equipment and software. The use of sensitive devices and automation of data processing make it possible to achieve high accuracy of calculations. The developed techniques are meant to operate in systems of support and decision-making and expert systems. The rapid assessment results can be used by supervisory agencies to evaluate the damage in case of accidents and failures of pipelines.

Smart control of gas distribution networks reliability

“…When evaluating and planning indicators the use of factor analysis based on the graph theory [4,5,[11][12][13][14] is essential. It solves two main problems of monitoring: the need for a comprehensive and, at the same time, detailed consideration.…”

“…The authors analyzed the problems of assessing the reliability of gas distribution networks in modern conditions [1][2][3][4][5][6][7][8][9][10][11][12][13][14]. Analysis of existing GDN operation systems shows that there is a range of issues impeding the qualitative monitoring of reliability and safety.Theseproblemsmayinclude:legalaspectsandboundariesofresponsibilitiesofoperatingco mpanies; architectural features of gas networks, difficult to assess and optimize; technical features of high, medium and low pressure networks; lack of modern assessment tools and measuring devices adapted to on-line monitoring systems, as well as lack of expert systems that can be integrated in complexes of satellite geo-monitoring and domestic control systems with the use of mobile expert notification systems for the end user.…”

Effect of section shape on frequencies of natural oscillations of tubular springs

“…To improve the characteristics of manometric springs, a number of spring designs with a cross-section and wall thickness varying along the central axis [6][7][8][9][10][11] are proposed, which may have better performance characteristics than springs of constant cross-section. There are tubular springs with a variable crosssection of the tube, both along the perimeter of the cross section, and along the longitudinal axis of the tube.…”

The Study of Electrical Energy Consumption in Cascaded Pumps for Pipeline Operations

“…Phase composition of gas condensate in pipeline has been studied using Bernoulli's theory . Oil leakages and emission during pipeline operations have been studied and quantitatively estimated by applying Bernoulli's theorem [24]. The method enables the leaked volume in a pipeline to be determined with great accuracy.…”
