舌形板波纹规整填料萃取塔的操作性能
Operation Performance of an SBW Stack Packed Extraction Column
摘要
Abstract
A new SBW structured packing was designed in order to meet high capacity extraction requirements. Hydrodynamic and mass transfer experiments were studied in a 100 mm diameter extraction column with the SBW structured packing, and kerosene-benzoic acid-water and 30% TBP (kerosene)-HAC-water systems were applied, respectively. Experiment results indicate that theoretical calculating of flooding throughout has high accuracy, and the calculated data agree well with the experiment data. The extraction column with the SBW structured packing shows high capacity and good mass transfer efficiency. The capacities at flooding point are between 90~150 m3·m-2·h-1 within the experimental range, and height equivalent to theoretical stage (He) values are between 0.6~1.4 m. The SBW structured packing may find possible applications in areas such as solvent deasphalting, lubricating oil refining in petrochemical engineering and phenol removal from wastewater in coal chemical industry.关键词
