Natural gas is a naturally occurring petroleum product and one of the major fossil energy
sources. It is composed of a complex mixture of hydrocarbon compounds and a minor …

Natural gas density is commonly measured by Coriolis density meters and gas
chromatographs, both of which are used to calculate the natural gas mass flow rate. In this …

The natural gas speed of sound (SoS) is needed for flowmeters calibration using sonic
nozzles. To determine SoS of real gases, the compressibility factor (sometimes called Z …

The current study presents an intelligent method for calculating natural gas compressibility
factor. The method requires three easily measurable properties including pressure …

In city gate stations (CGS) experimental facilities are currently employed to specify natural
gas compositions and subsequently calculate its density. Then, natural gas mass flow rate is …

In natural gas measuring techniques, the natural gas mass flow rate is usually measured
employing experimental facilities for density calculation, volume flow meters and other …

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 …

Natural gas is a mixture of 21 components and it is widely used in industries and homes.
Knowledge of its thermodynamic properties is essential for designing appropriate processes …

New viscosity measurements of three natural gas-like mixtures with compositions
resembling those of the Qatari North Field reservoir are reported in this work. The viscosity …

Density is an important property of natural gas required for the design of gas processing and
reservoir simulation. Due to expensive measurement of density, industry tends to predict gas …
