Natural Gas Compressibility Factor Table

Natural Gas Compressibility Factor Table FAQ

What is compressibility factor of gases?

Compressibility factor of gases is a thermodynamic property which is used to modify the ideal gas equation for real gases. PV = ZnRT, here Z is the compressibility factor for the given gas. The compressibility of a gas depends on the particular gas as well as temperature and pressure conditions.

What is the modifying factor for real gases?

The modifying factor for real gases is called the gas deviation factor or compressibility factor Z. It can be defined as the ratio of the gas volume at a given temperature and pressure to the volume the gas would occupy if it were an ideal gas at the same temperature and pressure.

How do you find the compound compressibility factor?

Compressibility factor values are usually obtained by calculation from equations of state (EOS), such as the virial equation which take compound specific empirical constants as input. For a gas that is a mixture of two or more pure gases (air or natural gas, for example), the gas composition must be known before compressibility can be calculated.

What is compcompressibility calculator?

Compressibility charts are based on empirical findings. For natural gas, compressibility factor depends on - temperature & pressure conditions, composition of the gas in terms of N 2, CO 2 and H 2 S content. This calculator helps in calculation of the compressibility factor for a natural gas based on Brill and Beggs Z factor correlation.
