| Abstract: |
| The performances of the fiber film extractor were investigated using a cold plexiglass pipe of 70 mm in diameter and 2630 mm in height. The influences of the operating and structural parameters on the flow and mass-transfer characteristics of the fiber film extractor were revealed. By analyzing the volume mass-transfer coefficient, the optimal operating flow-ratio and packed density were obtained. A flow model was built. Moreover, based on the theoretical analysis, Renault number was proposed as the design principle dimensionless number for fiber film extractor design purpose. The experimental results indicate that the optimal operating flow-ratio for a fiber film extractor is 5 while the best packed density is 2.8% ? |
