Phase Behavior and Compositional Analysis of Hydrocarbons Part 1: Methodologies and Preliminary Implementation

Muhammad Khurram Zahoor, Javaid Akhtar, Muhammad Haris

Abstract


Industries have to deal with complex mixtures of gas and liquids, where the proportion of gas and liquids can vary with the varying system conditions. This can be analyzed by performing flash and differential vaporization tests. Further, numerical methodologies can be used to interpret such fluid phase behavior. In this paper, such approaches have been discussed and Excel sheet has been developed for analyzing the phase change of different components existing in the hydrocarbon mixture. The study shows that the heavier components condenses into liquid rapidly as compared to lighter components with the increase in system pressure and after certain pressure this phase change become negligible. Such calculations generally entail iterative approach, so to have time efficient data designing in-house software is strongly required.

Keywords
