a gas permeation model (coupling model) has been developed which has the flexibility to be used for different membrane module configurations. the aim of this work is to predict the performance of a single stage gas separation process using membranes and provide a comprehensive description of process parameters like flow rates, composition, stage cut and stream pressure. the significant feature ...

The ability of Artificial Neural Network (ANN) for estimating the natural gas demand load for the next day and month of the populated cities has shown to be a real  concern. As the most applicable network, the ANN with multi-layer back propagation perceptrons is used to approximate functions. Throughout the current work, the daily effective temperature is determined, and then the weather data w...

China’s market-oriented reform supports the sustainable development of energy mix and low-carbon target, natural gas has bridged transition from traditional fossil to clean renewable energies. The third-party access policy, launched recently by market, drives decouple between trade transport. might lead transmission resources physical network not optimally used, which is caused contractual arra...

Natural gas is increasingly being used as a pure energy source. So it's valuable to reduce its total cost to be affordable for individual customer. In the past, interest was focused on efficient pipe network analysis method regardless of network cost; so many researches could be found for methods developed for network analysis. In contrast, very little researches could be developed to optimize ...

The modern electric power grid is a complex interconnected network of independent physical and electronic devices that utilize myriad technologies for communication between other devices and with centralized control centers. These technologies may be compromised by malicious parties which may, in turn, lead to degraded performance or a failure of the communications infrastructure, ultimately re...

In this paper, an Adaptive-Network-based Fuzzy Inference System (ANFIS) is used for forecasting of natural gas consumption. It is clear that natural gas consumption prediction for future, surly can help Statesmen to decide more certain. There are many variables which effect on gas consumption but two variables that named Gross Domestic Product (GDP) and population, are selected as two input var...

many large oil and gas fields in the most productive world regions happen to be fractured. the exploration and development of these reservoirs is a true challenge for many operators. these difficulties are due to uncertainties in geological fracture properties such as aperture, length, connectivity and intensity distribution. to successfully address these challenges, it is paramount to improve ...
