Abstract

The porous slurry integrates the excellent fluidity and mass/heat transfer properties of liquid

absorbents

and has the high specific surface area and well-developed pore structure of porous solid adsorbents

which is expected to become a new generation medium for CO

capture. To explore the indicators and energy consumption of CO

removal process using ZIF-8/DMAC porous slurry

a full-process model of slurry treating 300000 m

/h shift gas (H

/CO

) was established by Aspen Plus

based on the gas-slurry phase equilibrium experiments. The operating conditions and energy consumption per unit feed gas were analyzed and compared with the traditional propylene carbonate (PC) CO

capture process. The mean relative error between the simulation and the experiment solubility is less than 5.00%

indicating that the model results show good agreement with experimental data. For shift gas with 40% (mole fraction) CO

under the conditions of absorption pressure of 1.8 MPa

absorption temperature of 30 ℃

gas-liquid volume ratio of 80

and desorption pressure of 0.01 MPa

the H

recovery ratio of the ZIF-8/DMAC porous slurry process is 98.73% and the CO

capture ratio is 99.11%

and the CO

concentration in the purified gas is as low as 0.60%

and the energy consumption is 0.026 (kW·h)/m

. Compared with the PC process under the same CO

capture task

the ZIF-8/DMAC slurry process reduces solvent circulation by 50.10% and energy consumption by 38.10%

showing a clear energy-saving advantage.
