عنوان مقاله [English]
Hydrate formation is often undesirable in gas transmission and distribution systems and is often prevented from forming by various methods. In this study, the possibility of interrupting the flow of gas through the formation of hydrates or the formation of ice (controlled) at the desired location pipelines for repairs, the method of doing this, as well as how to resolve it after completion of repairs and safety considerations has been considered and the best approach has been evaluated based on the best or the nearest operational and operational criteria. All experimental data for natural gas are collected and the hydration formation temperature is simulated using artificial neural networks of the RBF model in the software environment of MATLAB. These results are compared with the experimental data, the mean square error for these artificial neural networks are less than optimal. In this study, the effect of the presence of nanomaterials on the formation of natural gas hydrates on simulated temperature and pressure parameters using artificial neural networks RBF (time series) has been empirically derived from valid papers In the following, one of the most practical cases has been studied and analyzed and expanded according to the formulation of mathematical constants and variables to be applied. For the simultaneous formation of hydrate and ice inside the tube, it is necessary to raise the temperature of natural gas from 60°F to 32°F, for this purpose, the cooling fluid of the device is nitrogen liquid at a temperature of -195.79 °C.
