absolute present derivation (AAPD) less than 0.7%. Finally the effect of a few parameters including: friction factor, natural gas composition and decreasing and increasing demand have been studied. Results show that Weymouth and AGA equation predict highest...

The aim of the current work is to investigate the effects of natural gas compositions on reciprocating compressor performance numerically. A numerical model has been built based on first law of thermodynamics, mass balance, AGA8 EOS (Equation...

dropped on the coldest day of the year due to the increase in natural gas demand. In addition, the effect of natural gas composition on node pressure investigated. Results show that the natural gas with higher molecular weight has a lower pressure in all...

It is vital for the designers of the throttling facilities to predict natural gas temperature drop along a throttling valve exactly. Generally, direct prediction of the temperature drop is not possible even by employing ...
