Sulfolane aromatic hydrocarbon solvent solubility, high selectivity, high thermal stability, and no corrosion of equipment. Therefore, continuous reforming - aromatics extraction unit using sulfolane as the solvent, use extraction method recovery of high purity benzene from reformate oil, toluene, xylene and C9 aromatic hydrocarbons, sulfolane size of impurity content directly affect pumping sulfolane solvent to mention the effect is continuous reforming - an important control aromatics extraction unit.
Tengzhou City Technology Co., Ltd. Xiangying analysis method for determination of industrial sulfolane impurities using GC7990 gas chromatography method and the experimental conditions were discussed. The results show that the recovery rates between 97.1% ~ 98.8%, to meet the requirements analysis, guidance workshop production.
环丁砜溶剂对芳烃溶解度高,选择性好,热稳定性高,且对设备无腐蚀。因此,连续重整-芳烃抽提装置采用环丁砜作为溶剂,利用抽提法从重整油中回收高纯度的苯、甲苯、二甲苯和C9芳烃,环丁砜中杂质含量的大小直接影响环丁砜溶剂的抽提效果,是连续重整-芳烃抽提装置重要的控制。
滕州市翔鹰分析技术有限公司采用GC7990气相色谱法测定工业环丁砜中杂质含量的分析方法,并对该方法的实验条件进行了探讨。结果表明,该方法的回收率在97.1%~98.8%之间,能够满足分析方法要求,指导车间生产。
