The air blow-out method of extracting bromine from seawater or brine is widely used at home and abroad. The key parameter in this unit operation is the vapor-liquid equilibrium data (T, x, y) for brominebrine system, which were obtained with the Bubble Equilibrium equipment at 10 and 20℃ in this paper. The experimental equilibrium data were carried out by using Margules Equation for liquid phase and ideal equation for gas phase, and the nonlinear least square method was used to regress the parameters of Margules model for the system. It showed good consistency for the calculated data from Margules model and the experimental data.
Key words: Bromine / air blow-out method / vapor-liquid equilibrium (VLE)
