Popis: | Gas hydrates are formed in various natural gas transmission facilities and gas processing equipment in oil and gas fields, refineries, petrochemical plants and chemical industries when water and natural gas combine at sufficiently low temperatures and high pressures condition. Estimation of the temperature and pressure at which hydrates are formed is the first measure that is usually taken to prevent hydrate formation. In this paper, two data-driven models namely artificial neural network (ANN) and Adaptive Neuro Fuzzy Interference System (ANFIS model), were developed as an alternative instruments that draw on empirical data to estimate hydrate formation pressure for various gas systems. To this end, statistical parameters were used to determine the optimum structure of each data-driven model applied on these systems. The results obtained from neural network ANN and ANFIS models were compared to the experimental equations According to the performance criteria, the ANFIS model outperforms the ANN model in all cases. The results also showed that the ANFIS model was in more agreement with experimental data than empirical equations. |
