Analysis And Evaluation Of CNG Station Gas Storage Well

In recent years, the proportion of natural gas increases by large scope in national consumption structure of energy sources. And the natural gas as the cleanly sources to be used for automobile has been rapidly developed - CNG automobile not only reduces environment and noise pollution, but also saves running cost. At the same time, under the lead of national energy sources protection policy, the quantity of CNG automobile continuously increases in recent years, which brings the CNG gas station rapidly developing. And it's very important whether gas storage well, as the most widespread way in three main gas storage ways for CNG gas station, can insure safe, steady, perennial and full-load running. Thus, it's useful to analyze the security of natural gas storage well, for ensuring the gas station's security, maintaining gas station's the service, advancing the optimization of gas station's gas storage way, and assuring the healthy development of city construction.According to the features of our country's gas storage well, using Statics analysis technique of pressure vessel for reference, and basing on the relevant research work of gas storage well at home and abroad, this thesis sets up mathematics model, and usefully explores the analysis of gas storage well's security. The main achievements and features of the thesis as below:1) Through collects the domestic and foreign related research results technical data, analyzed several kinds of gas storage way merit and the defects . Through the contrast explained that the gas storage well takes our country gas station gas storage way is more better than other way. 2) Through analyze the traditional gas storage well's common breakdown question's and to have the breakdown reason and to elaborate the pressure vessel gas storage well produced the corrosion mechanism. Summarized the gas storage well have the corrosion form, as well as have the corrosion influencing factor.3) Used existing software ANSYS to establish the domestic high-pressured underground gas storage well part's simplified model. And carry on the analysis to the existing gas storage well body's internal surface's corrosion, And has carried on the three dimensional model to the gas storage well body, carried on the analysis from the statics to the gas storage well internal surface corrosion area as well as the corrosion depth to the gas storage well stress's influence. In order to provide technical support for the gas storage well in the design selection and the routine maintenance.To further enhance our country natural gas highly effective use, promotes the CNG automobile's application and gas station safely. Reduced potential threat which the gas storage well creates. In order to reduce the urban safe potential danger and the contamination control and so on provides the engineering factor and the support.
