Influence of Hollow Fiber Membrane Membrane Structure on the Effect of Flue Gas Decarbonization of Ships
To achieve carbon dioxide reduction in the shipping industry,this paper explored the effects of factors such as membrane filaments filling rate,length of membrane filaments,number of membrane filaments,inner diameter of membrane filaments,thickness of membrane filaments,po-rosity of the membrane filaments and membrane filaments microporous aperture on the effect of de-carbonization of the flue gas of ships.The experiments showed that:when the membrane filaments filling rate was 60％,the length of the membrane filaments was 700 mm,the number of membrane filaments was 700,the inner diameter of the membrane filaments was 0.52 mm,the thickness of the membrane filaments was 0.25 mm,the porosity of the membrane filaments was 55％and the diameter of the micropore size was 0.10 μm,the highest removal rate of carbon dioxide in ship smoke could reach 83.38％.And came to a conclusion:the inner diameter and wall thickness of the membrane filaments were inversely proportional to the decarburization efficiency;membrane filaments filling ratio,filaments length,number of filaments,filaments porosity and filaments mi-croporous aperture were positively related to decarburization efficiency for the application of polytetrafluoroethylene hollow fiber membrane in the decarbonization of the flue gas of the ship.
