| Summary: | The GLCC (Gas-Liquid Cylindrical Cyclone) is an effective equipment used to separate gas and liquid mixtures. In this work, the performance of the turbulence models RST and k-e was evaluated in terms of the correspondence with the experimental data. Of which the RST model achieved a better performance in 3 of the 4 items evaluated. Subsequently, a complete factorial design 2^3 was carried out, in which the effect of the Reynolds, Morton and Etèovos dimensionless numbers were evaluated through the variation of physical properties such as viscosity, density and surface tension. Obtaining that the number of Reynolds and Morton have a significant (a= 0.005) and negative polarity influence in the volumetric fraction of liquid in the gas phase resulting from the equipment. Finally, it was evaluated that the model obtained from the experimental design was correct in light petroleum where a prediction of the volumetric fraction of LCO value was obtained with an error of 26.7%. |
