Abstract

In the process of CO2 separation from natural gas, research has been done by various parties. Even though they were successful to a certain extent, a far more clear and optimized process is being searched for. In this study, simulation software is used to replicate experimental data. Supersonic nozzles are used, as there is a reduction in the pressure and temperature of the gas when it flows through a converging–diverging nozzle, and the condensation process can take place. The aim of this study is to find a set of parameters that can be used to achieve a higher efficiency in CO2 condensation. At the conclusion of this study, a sharp pressure drop, of more than 50%, is observed when using lamina flows for both Ideal and Peng-Robinson CO2. When the K-Epsilon turbulence model is used, the pressure drop is only 25%. CFD simulations were conducted on ANSYS CFX. Past literature has shown how achievable the partial condensation of both natural gas mixtures containing CO2 and pure CO2 is.
