Carbon dioxide (CO2) emission from burning fossil fuels has been identified as the major contributor to the increase in atmospheric CO2 levels that can potentially lead to global climate changes. Among main methods that are being developed for CO2 capture and separation (CCS), CO2 adsorption is of great interest because of its low energy consumption, low equipment cost, and ease of application. In this work, a new simple-to-use correlation, which is easier than current available models involving a large number of parameters and requiring more-complicated and longer computations, is presented to predict accurately the CO2 adsorption isotherms for a molecular sieve as a function of temperature and CO2 partial pressure. This correlation predicts the CO2 adsorption isotherms for CO2 partial pressures and temperatures up to 120 kPa and 470 K, respectively. The promising method to develop correlation for accurate prediction of CO2 adsorption isotherms could be extended for CCS for the wide range of adsorbents, including various molecular sieves, simply by readjusting the tuned coefficients. The average absolute deviation between reported data and the proposed correlation is approximately 4%.
