Abstract In city gas pressure reducing stations, in order not to hydrate natural after a sudden drop pressure, the temperature is raised by heater. The increase such that drop, inside pipes does freeze. These heaters are burning and very high consumption, because they use fossil fuels, produce environmental pollution. Accordingly, this research, solar energy will be used preheat gas, which for ...

The present sought to draw a comparison between Model Predictive Control performance and two other controllers named Simple PI and Selective PI in controlling large-scale natural gas transport networks. A nonlinear dynamic model of representative gas pipeline was derived from pipeline governing rules and simulated in SIMULINK® environment of MATLAB®. Control schemes were designed to provide a s...

In this study, operation of compressor station has been investigated by exergy approach. Exergy analysis is a thermodynamic method which shows the irreversibility of a system quantitatively. Gas compressors are used to compensate the pressure drop along the gas pipeline significantly. The compression process causes temperature rise of gas; in this regard gas cooler is applied to reduce the temp...

Along with several other nuclear physics laboratories around the world, the NSCL has undertaken the challenge of stopping a radioactive ion beam in order to make low-energy beams for experiments that require nearly thermal beam energies (precision mass measurements, laser spectroscopy, etc.). As part of the LEBIT (Low Energy Beam and Ion Trapping) Project at the NSCL, a gas stopping station is ...

this study mainly focuses on enhancing the overall efficiency of gas transmission networks. the authors developed a model with detailed characteristics of compressor and pressure reduction stations. following this, they suggested three different systems with gas turbine including: organic rankine cycle (orc), air bottoming cycle (abc), and abc along with steam injection (si-abc). in addition, u...
