Pressure in the deep-water pipeline is an important parameter that should be carefully predicted to control natural gas transport petroleum industry. However present methods predict pressure along are complex and time-consuming. Some even ignore formation of hydrate leading inaccurate prediction. In this work, we proposed a model considering reduction radius induced by hydrate. The was validate...

To obtain the accurate transient states of big scale natural gas pipeline networks under bad data and non-zero mean noises conditions, a robust Kalman filter-based dynamic state estimation method is proposed using linearized flow equations in this paper. Firstly, model built. Since are less than states, boundary conditions used as supplementary constraints to predict states. increase measuremen...

Natural gas could become one of the most important and strategic energy source in the years to come, even if the renewable sources growth will play a fundamental role in the “next green power energy”; however natural gas has the chance to assure a continuous and reliable energy supply on a economically viable, long term base span. Potential routes for gas export from giant mid-continental field...

Transmission of natural gas from its sources to end users in various geographical locations is carried out mostly by transmission pipeline networks (NGTNs). Effective design and operation NGTNs requires insights into their steady-state and, particularly, dynamic behavior. This, turn, calls for efficient computer-aided approaches furnished with accurate mathematical models. The conventional meth...
