... Abstract Gas transmission pipes are required to have sufficient material toughness at their minimum working temperature, (here, called Minimum Design Metal Temperature, MDMT) to avoid brittle fracture. This paper proposes a new practical approach in predicting the MDMT for buried natural gas...

... in biofuel and biogas production from various kinds of algae. In the U.S., 5% of the natural gas utilized in the electric power sector and 56% of the natural gas in transportation can be directly replaced with biogas. In a typical Californian household, around 50% of the 354 therms Natural Gas energy...

..., if they are capable of demonstrate anticipation and low false alarm rates. A regional Natural Gas transportation system deals with these types of drawbacks. While the improvements are carried out, some effort should be done in order to improve the safety in operations. In this paper a data-driven technique was used...

... 01 05 2012 In this paper, the performance of a natural gas HCCI engine is studied through a thermodynamic model including detailed chemical kinetics. Then the influence of using formaldehyde as an additive on the engine characteristics has been investigated. Results show...

... 24 08 2009 The present study is concerned with measuring and simulating the formation process of carbon black in a natural gas furnace. Carbon black concentrations in the furnace have been measured by the gravimetric method. Fluent CFD software has been employed for numerical...

... 23 05 2008 The work evaluates the combustion of natural gas in a cylindrical furnace. The Generalized Finite Rate Reaction Model was selected for predicting the reactions. Two situations were considered. In the first case the combustion of the fuel was predicted by a single global...

... combustion of Methane and Hydrogen. The natural gas can be represented as the Methane (CH 4 ), which is the main ingredient. The simulation evaluations were done by increasing the initial concentrations of H 2 , changing the initial temperature (inlet temperature), or varying the equivalence ratio...

... 28 01 2008 The paper describes the background of the European Harmonized Reference Value for the cubic meter of Natural Gas at high pressure, which is in use in Germany, The Netherlands and France since May 4 th , 2004. The harmonization process began on November 1 st , 1999 between...
