倾斜泡沫相的角度及长度对泡沫分离十六烷基三甲基溴化铵的影响
Effects of the Angle and the Length of the Inclined Foam Phase on Foam Fractionation of Cetyl Trimethyl Ammonium Bromide
摘要
Abstract
The foam fractionation column of inclined foam phase was adopted for enhancing the foam phase drainage. The traditional column of vertical foam phase was used as the contrastive column and CTAB (cetyl trimethyl ammonium bromide) was used as the model aqueous solution to be fractionated. The effects of tilt angle and length of inclined foam phase on enrichment ratio and recovery percentage of CTAB were studied. The experimental results show that the tilt angle and length of inclined foam phase have significant impact on the foam fractionation. As the tilt angle increases, enrichment ratio increases at first and then decreases. However, recovery percentage decreases and then increases. Enrichment ratio and recovery percentage reach their maximum and minimum values separately when the tilt angle is 40°. With increasing the length of inclined foam phase, enrichment ratio and recovery rate increase and decrease respectively, and then become constant. The suitable length of inclined foam phase was determined to be 650 mm. Under the conditions of loading liquid volume 250 mL, initial concentration of CTAB 0.07 gL1 and gas flow 200 mLmin1, the enrichment ratio of CTAB obtained by the fractionation column of inclined foam phase with the optimum tilt angle and suitable length of inclined foam phase is 16.7, which is 1.8 times as much as the enrichment of CTAB obtained by the contrastive column.关键词
