The phase equilibrium of mixtures of Yukawa and charged Yukawa particles was analyzed using Gibbs ensemble Monte Carlo (GEMC) simulation and the mean spherical approximation (MSA). A coupling constant was used to compare the strength of the Coulomb energy with Yukawa attraction. It was shown that for low coupling constants a classical vapor-liquid phase separation appears with a good agreement between GEMC and the MSA. The results show that for high coupling constant, a phase separation between a salt poor and a salt rich phase occurs that resembles the phase equilibrium behavior of the solvent primitive model.
