摘要: Abstract This study investigated the mass transfer performance of rotating packed bed (RPB) with blade packings in carbon dioxide (CO 2 ) absorption by sodium hydroxide (NaOH) solution. The overall volumetric gas-phase coefficients ( K G a were compared using 1 vol% CO and 1 mol/L NaOH solution for three RPBs effects rotational speed, gas flow rate, liquid rate. As expected, speed positively affected values all RPBs. Furthermore, obtained results indicated that increased as inner radius was outer decreased. Moreover, an increasing rate According to comparison RPB structured packings, had applicability removing from exhaust gas.
