The PSA process is one of the viable technologies for CO2 capture from large CO2 generating sources. It is generally known that a two-stage PSA process is required to recover 99% CO2 from flue gas containing 10-15% CO2. The aim of this research is placed in re-evaluating the economy of the two-stage PSA process for CO2 capture using zeolite 13X as adsorbent through numerical simulation and optimization. The performance curves of commercial vacuum pumps were used for realistic calculation of the operating cost. In addition, parameters such as mass transfer coefficients that have significant effects on the process behavior but whose values are only ambiguously known were estimated through the experiments. For numerically stable calculation, a novel numerical procedure using gradient-directed adaptive predictive collocation with a cubic spline interpolation function and far-side boundary conditions were adopted. Economy of the PSA process was evaluated for the optimized process conditions as a function of CO2 contents of the inlet flue gas and CO2 recovery rate.
