Mathematical Representation of Natural Gas Compressibility Factors

This article presents a new method of calculating natural gas compressibility factors. Based on compressibility charts commonly found in graphic form, the article describes how to mathematically convert the graphs into smooth functions which can be easily applied to computers. The method applies to natural gases, even those containing hydrogen sulfide and carbon dioxide, over a wide range of opertating conditions and compositions.

Spatial Equation of State for a Single-Phase Fluid

This article presents an alternate method of representing the characteristic equation of state of a single-lphase, pure fluid. The method is based on a mathematical technique that utilizes multiple three-dimensional surface functions, linked together to emulate the overall smooth and continuous behavior of any fluid. The single-phase spatial equation of state is generated from given phase behaviour data points, which provide very accurate pressure-temperature-density values within the region of interest.
