Study and analysis the fuel leakage security of current LNG alternative fuel bus. Do the simulation on surrounding concentration and temperature of LNG bus fuel tank leakage by Computational Fluid Dynamics (CFD). By analyzing the influence of three different bus velocities, 0km/h, 30km/h and 80km/h, we have the conclusion from the simulation that when the bus gets faster, the influence of surrounding...
With natural gas deposits now being extracted from previously unattainable shale formations, natural gas transmission networks throughout North America are required to be more dynamic in terms of transportation receipt/delivery points than anytime in the past 50 years. New production sources must access interstate transmission and storage lines to deliver natural gas to market. System modifications...
At present, pipeline natural gas (PNG) and liquefied natural gas (LNG) are the main technologies for natural gas storage and transportation. But it is not economic to explore those scattered, remote and limited high well-pressure gas fields by PNG and LNG technologies. So the new technology should be investigated. Natural gas hydrate (NGH) approach is expected to resolve these problems. In this paper,...
We examine the problem faced by owners of gas storage contracts of how to manage the injection/withdrawal schedule of natural gas, given historical price behavior and a predictive model of future prices. We describe a hybrid price prediction model that combines a support vector machine technique with a stochastic model for short and long-term gas prices, respectively. We present a theoretical result...
In the oil-gas prediction of seismic reservoir, the traditional method directly classify by attribute. However, the dimension of input information is so large that the calculation is time-consuming, the storage capacity demanding and the network structure complex. Moreover it is easy to be caught in local minimum in the sample learning. Therefore, a method of oil-gas prediction in seismic reservoir...
