This paper discusses a Reliability, Availability, and Maintainability (RAM) independent assessment conducted to support the refurbishment of the Compressor Station at the NASA Langley Research Center (LaRC). The paper discusses the methodologies used by the assessment team to derive the repair by replacement (RR) strategies to improve the reliability and availability of the Compressor Station (Ref...
Natural gas is rapidly growing in global importance both as a primary energy source and a feedstock for downstream industry. Therefore, needs for natural gas transportation from production zones to consuming areas are ever increasing. Natural Gas transmission through pipelines is the oldest and most common method for high capacities gas transmission. These transmission systems are very capital intensive,...
A global optimal mathematical model of increasing pressure for large-scale territorial gas pipeline network is established, and it takes maximum annual benefits of pipeline network system as objective function after comprehensively considered the upstream gas producing conditions, the downstream gas utilizing conditions, the balance equation of nodal flow capacity, and the power, amount, position...
A new plant module combusts at approximately 1150degC temperature 180 metric tons of municipal solid waste and generates a minimum of 144 MWh (megawatt hours) of electricity, as well as 912,000 liters of potable water a day. The waste-processing and electricity generation new pilot plant comprises: 4 waste-processing furnaces (reactors) with the capacity 2.5 tons of waste per hour each; gas turbine...
In this paper, ant colony optimization algorithm (ACOA) is proposed to solve the problem of how to efficiently operate a natural gas pipeline under steady state assumptions. The system is composed by compressing stations linked by pipe-legs. For each station, it is necessary to find the operating turbocompressors optimal values and the discharge pressures ones to minimize the total amount of fuel...
Gaslift is the way of well utilization when the gas arriving from the surface or from the fiery seam in the section of the same well is introduced into the flow of layer liquid to decrease the density of gas-liquid mixture, as the result the pressure at the breast of oil layer becomes sufficient not only for the provision of the given oil selection from the well but also for the product transporting...
