摘要

The statistical associating fluid theory (SAFT) equation of state is employed for the correlation and prediction of vapor-liquid equilibrium of CO₂ + H₂O binary system for a wide temperature (10-300 掳C) and pressure (1-600 bar) range. To make the equation applicable for these temperatures and pressure ranges, effective numbers of segments and energy parameters have been co-related with reduced temperature and pressure. Simple mixing rules have been applied to obtain binary interaction parameter. The results were found to be in satisfactory agreement with the literature data except in fully miscible regions.
