RISPerformance assessment of vortex tube and vertical ground heat exchanger in reducing fuel consumption of conventional pressure drop stations
In natural gas pressure drop stations, before pressure dropping specially in cold seasons, the natural gas is preheated to prevent gas hydrate formation. Indirect water bath heaters employed for preheating. The heaters ...
Integration of vertical ground-coupled heat pump into a conventional natural gas pressure drop station: Energy, economic and CO2 emission assessment
City gate stations receive high pressure natural gas and decrease the pressure by throttle valves. Concurrent with the natural gas pressure reduction, the temperature also drops. Thus, to prevent blocking of the downstream ...
Performance assessment of a natural gas expansion plant integrated with a vertical ground-coupled heat pump
In the present paper, a vertical ground-coupled heat pump system is proposed for energy saving in a natural gas expansion plant. Such plant is a modern type of conventional natural gas pressure drop station. Unlike the ...
A numerical and experimental study on the energy efficiency of a regenerative Heat and Mass Exchanger utilizing the counter-flow Maisotsenko cycle
In this work, a numerical and experimental study is performed to evaluate the affecting variables on
energy efficiency of a novel regenerative evaporative cooler utilizing dew-point indirect evaporative
cooling. For ...
Numerical simulation of pressure pulsation effects of a snubber in a CNG station for increasing measurement accuracy
Local natural gas companies in Iran employ turbine flow meters to measure natural gas which
is delivered to Compressed Natural Gas (CNG) stations at low pressure. The stations, then, utilize
reciprocating ...
