On the Issue of Gas Leakage Evaluation in Section of Gas Field
摘要
In the process of long natural gas transmission, the pipeline leakage often occurs due to various reasons, the aperture of the leakage is large, small, the location of the leakage point is difficult to predict, causing pollution to the environment, waste of energy. Through the direct and indirect causes of natural gas pipeline leakage accident, the main factors of pipeline leakage are analyzed, and then through the CFD software to simulate the leakage time and dangerous area identification, and get the distribution of natural gas in the atmosphere after natural gas pipeline leakage. The study shows that: after this kind of pipeline leakage, the most important thing is to control the leakage time and dangerous area identification, at the same time, supporting the natural gas pipeline leakage monitoring system and pipeline leakage prevention management measures, to reduce the harm of pipeline leakage. At the same time, He8 solid waste of YA gas field was sampled, its performance characteristics and pollution characteristics were analyzed, and the solid waste of He8 well of the gas field was studied. Zero-price metal catalyst was selected by the experimental reduction method to decompose pollutants in the copper catalyst. It show that when the experimental conditions is
