• Based on local composition, the Wilson equation, NRTL equation and Bruin equation are discussed. A new two-parameter equation gE/RT=x1x2{W12/x2+x1exp(-W12)+W21/x1+x2exp(-W21)}is proposed. This equation maybe applied to most systems, as can the three-parameter NRTL equation, though it has the limited use to the systems having the large negative deviation from Raoults law. This equation is tested and compared with other equations including van Laar equation for five binary and two ternary systems and good results are obtained.
