环丁砜抽提蒸馏工艺在惠州炼油芳烃联合装置的应用

环丁砜抽提蒸馏分离成套工艺(SED)在中海炼油化工有限责任公司惠州炼油分公司芳烃联合装置取得成功工业应用,标定及运转结果表明,该工艺技术先进,流程合理,各项技术指标均达到设计要求及合同的保证值。苯和甲苯质量达到了国家优级品标准,回收率分别达到了99.8%和99.9%。投资、能耗及物耗较国外同类技术显著降低。

INDUSTRY APPLICATION OF SULFOLANE EXTRACTION AND DISTILLATION PROCESS AT HUIZHOU REFINERY

The commercial application of sulfolane extraction and distillation (SED) technology developed by Research Institute of Petroleum Processing was successfully carried out on the 780 kt/a PX project of Huizhou Refinery. The performance test and long-term running results showed although the feed compositions were different from the design values in some items, due to the advanced process technology and reasonable process scheme, all the technical indexes met the design targets. The qualities of benzene and toluene reached the requirements of National Standard for super grade products; the recovery rates of benzene and toluene were 99.8% and 99.9%, respectively. The investment, energy consumption and material consumption of SED process were lower than those of the other similar technologies.
