A simple phase equilibrium equation is proposed to describe the vapor-liquid equilibrium of some non-ideal solutions. The linear least square method is used to determine the undetermined coefficients in the equation. The equilibrium composition of the vapor-liquid phase calculated by this equation is in good agreement with the experimental data. The equation, in combination with Yu Guocheng and CoullJ equations, can be used to approximate the vapor-liquid equilibrium of more non-ideal solutions. The formula for calculating the minimum theoretical plate number and the mass transfer unit number is derived using this equation. Some applications in distillation calculation
