Abstract

This study addresses a proposal for mathematical modeling of the homogeneous condensation phenomenon that occurs in supersonic separators. Such equipment aims to separate contaminants in gas mixtures, such as in the exploration of natural gas in pre-salt reservoirs. In this scenario, the separation of carbon dioxide, present as a contaminant of methane gas, is of great economic and environmental interest. Computational simulation is an important tool to make the construction of more efficient equipment possible, where the condensation of the contaminant and its removal can be improved. Therefore, this work reviews the current mathematical models for the phenomenon and proposes its implementation in a compressible flow solver using the OpenFOAM framework. This solver is first validated against experimental data available in the literature to be used in an initial analysis of a new design of a supersonic separator.
