We propose a new formulation for the attractive term of van der Waals type EOS written in the compression factor form. The formulation has three model constants at the critical temperature. One is determined from experimental data, and the other two are given by satisfying constraints on the critical compression factor and its first derivative at the critical point. An original temperature dependence function is also developed. The EOS along with the new formulation has the ability to reproduce the gas phase fluid property within 0.5% of the relative error as compared with experimental data.
