Popis:	The appropriate design, construction, and operation of carbon capture and storage (CCS) and enhanced oil recovery (EOR) processes require a deep understanding of the resulting phases behavior in hydrocarbons-CO_2 multi-component mixtures under reservoir conditions. To model this behavior a nonlinear system consists of the equation of states and some mixing rules (for each component) needed to be solved simultaneously. The mixing usually requires to model the binary interaction between the components of the mixture. This work employs optimization techniques to enhance the predictions of such model by optimizing the binary interaction parameters. The results show that the optimized parameters, although obtained mathematically, are in physical ranges and can reproduce successfully the experimental observations, specially for the multi-component hydrocarbons systems containing Carbon dioxide at reservoir temperatures and pressures Comment: To be published in Cadernos do IME - S\'erie Matem\'atica da UERJ
