摘      要：A mathematical model for phase equilibrium prediction of multi-component gas separation process inside a supersonic separator is established and an efficient numerical solution method is designed. The model and the numerical method are then used to predict the phase equilibrium characteristics and the separation performance of a field test natural gas supersonic purification separator. The predicted results are generally in good agreement with the field test measurements, which proves that the phase equilibrium model and the solution method are both reliable and accurate, and can be used for the prediction of the vapor and liquid phase equilibrium and the separation performance and the configuration optimization of supersonic separator.
