ABSTRACT = {A hybrid system combined with a non-contact membrane and bubbling absorption is proposed to capture CO<sub>2</sub>
from flue gas. The non-contact way of membrane and liquid absorbent effectively avoids the reduction of gas
diffusion flux through the membrane. High-porosity ceramic membranes in hybrid systems are used for gas-solid
separation in fuel gas treatment. Due to the high content of H<sub>2</sub>O and cement dust in the flue gas of the cement
plant, the membrane is hydrophobically modified by polytetrafluoroethylene (PTFE) to improve its anti-water,
anti-fouling, and self-cleaning performances. The results show that the diffusion flux of CO<sub>2</sub> through the membrane is still higher than 7.0 × 10<sup>−3</sup> mol/m<sup>2</sup>
s (20% CO<sub>2</sub> concentration) even under the influence of water and
cement dust. In addition, slaked lime selected as the absorbent is cheap and the product after bubbling absorption
is nano-scale light calcium carbonate. To sum up, the hybrid system combining non-contact membrane and bubbling absorption is expected to be used to capture carbon dioxide from the flue gas of the cement plant.},
