摘要
重点介绍了芳烃抽提的两种技术,比较了液液抽提、抽提蒸馏技术的优缺点、原料适应情况,及不同抽提技术采用的溶剂和流程特点;分析总结了液液抽提技术和抽提蒸馏技术在芳烃生产中的应用情况及各技术对三苯收率、产品纯度的影响。
This essay introduces two aromatic extraction technologies,liquid-liquid extraction and distillation ex- traction,and compares their advantages and disadvantages, suitability to different feedstock,and solvent and process characteristics.The application of these two technologies in aromatic production as well as their influence on light aro- matics yield and product purification is also analyzed.
