Abstract
An experimental and simulation study using a packed column for CO(2)sorption was conducted. The adsorption data of CO(2)sorption from CO2/N(2)mixture using activated carbon (NORIT RB1) were obtained at different operating conditions. The sorption equilibrium and breakthrough profiles were produced with a total pressure of 1.25 bars. The breakthrough and saturation time decreased with increasing temperature, feed rate, and inlet CO(2)concentration. A linear driving force (LDF) model for mass transfer was used to calculate the mass transfer coefficient and reproduce the breakthrough curves. The findings of the LDF model were compared with experimental data produced at various operating conditions to predict the breakthrough curves. The experimental and predicted findings were analyzed by ascertaining the determination coefficient and mean error. The model consistently reproduced all the breakthrough curves and may be considered adequate for predicting the CO(2)separation from a CO2/N(2)mixture withR(2) > 0.97 and mean error less than 5% under all the operating conditions.
