Determination of Natural Gas Losses Based on Incomplete Information About Damaged Pipeline

International and European trends soon foresee a significant reduction of carbon dioxide and methane emissions and a transition to technologies based on renewable energy sources. One of the strategic tasks of the sustainable development of gas transportation systems is to reduce the technological consumption of natural gas, including methane leaks into the atmosphere from gas transportation systems. Therefore, the article considers very important issues of technical, economic and environmental protection related to the detection and reduction of possible leaks of natural gas from damaged gas pipelines. An improved mathematical model of steady-state gas movement is proposed, which enables the calculation of gas parameters along the gas pipeline and at the point of damage. Using the equations for calculating the gas flowrate during its leakage through the hole into the air enables the determination of the amount of gas loss through the damage. A methodology has been developed for determining the amount of gas lost from a gas pipeline with existing damage under conditions of incomplete information about the gas pipeline. The obtained results make it possible to increase the accuracy of determining the amount of losses and reduce the time of damage detection, localization and elimination.
