| titleOfInvention | Hollow fiber composite membrane for carbon dioxide / methane separation in biogas purification process, membrane module including same and method for manufacturing same |
| abstract | The present invention relates to a hollow composite membrane for carbon dioxide / methane separation coated with an organopolysiloxane copolymer having a repeating unit grafted with polyethylene glycol or polyethylene / propylene glycol on the surface of hollow fiber membranes made of a glassy polymer, and a membrane module to provide. In addition, the present invention comprises the steps of: i) dissolving the glassy polymer in an organic solvent to obtain a polymer solution; ii) mixing an additive to the polymer solution obtained in step i) and stirring to obtain a uniform spinning solution; iii) providing a hollow fiber membrane by spinning the spinning solution obtained in the step ii) through a double spinneret; And iv) coating a solution of an organopolysiloxane copolymer having a repeating unit grafted with polyethylene glycol or polyethylene / propylene glycol on the surface of the hollow fiber membrane in step iii). do. The hollow fiber composite membrane produced by the present invention has an advantage in that the permeability of carbon dioxide is greatly improved and the carbon dioxide is selectively separated and removed from the mixed gas of carbon dioxide and methane in the biogas purification process and the efficiency of the separation process is improved. |
