Investigate of mass transfer of CO2 absorption into the mixed solution of piperazine and diethanolamine in a packed column
In our work, the aqueous solution of diethanolamine and piperazine was used to capture CO<sub>2</sub> from a mixture of N2 and CO<sub>2</sub> with a packed column. The effect of PZ/DEA mass ratio, gas flow rate, liquid flow rate, absorption temperature and CO<sub>2</sub> content in the mixed gas on the overall volumetric mass transfer coefficient (K<sub>GaV</sub>) were discussed, respectively. The results showed that the value of KGaV increases with the increasing of PZ concentration, gas flow rate, liquid flow rate, respectively. However, K<sub>GaV</sub> value decreases as absorption temperature and the CO<sub>2</sub> content of inlet gas increases. The results indicated that the addition of piperazine can effectively improve the mass transfer effect of CO<sub>2</sub> absorption into DEA aqueous solution.
