Abstract A hybrid system combined with a non-contact membrane and bubbling absorption is proposed to capture CO2
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 H2O 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 CO2 through the membrane is… More >
