Therefore a simultaneous optimization algorithm is proposed to develop an accurate but compact engineering \EOS\ for wide range of fluids with one single functional form. The algorithm is based on a simulated annealing method, and operates on different fluids at the same time to achieve the best average results. A 14-term \EOS\ is developed based on this algorithm that has good accuracy for selected non-polar and polar fluids. The resulting equation is compared with two different 12-term \EOS\ developed by Span and Wagner, one for polar fluids, the other for non-polar fluids. The new 14-term \EOS\ also gives good predictions for some associating fluids such as alcohols and water.
