About this document
Generalized Alpha Function for PR CEOS by mohsen is a document available to read on EtoBox.
The document presents a new generalized alpha function for the Peng-Robinson cubic equation of state to improve vapor pressure predictions, especially for heavy hydrocarbons. It discusses limitations of previous alpha functions, which involve higher-order polynomials in the acentric factor or require component-dependent parameters. The new approach aims to develop an alpha function that is a linear function of the acentric factor to better extrapolate to heavy hydrocarbons.
