hydrates are crystalline compounds similar to ice, with guest molecules like methane and ethane trapped inside cavities or cages formed by the hydrogen bounded framework of water molecules. these solid compounds give rise to problems in the natural gas oil industry because they can plug pipelines and process equipments. low dosage hydrate inhibitors are a recently developed hydrate control tech...

the purpose of this research is to found the impact of built area and occupant number on winter gas consumption in the residential building sector of iran, shiraz.sothe annually and monthly gas consumption data through 19 houses were analyzed to achieve the heating energy consumption and operation month.the average operation months of gas heating consumption were from first of november up to en...

Considering the fact that natural gas is a widely used energy source,  the prediction of its consumption can be useful (Derek LAM, 2013). As Iran has one of the largest gas reserves in the world, its consumption in the country can affect the worldwide price of gas, Therefore, the current research is useful both from economic and environmental point of view. ...

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...

This paper deals a universal prediction system based on AI techniques and classical statistical analysis. It describes principles and methodologies used within the system. Further it discusses internal structure of the system and general conditions for its successful use. Despite of system wide applicability, originally it was conceived as a system for prediction of gas consumption. A practical...
