环保型芳烃橡胶填充油抽提工艺开发与工业应用

DEVELOPMENT AND COMMERCIAL APPLICATION OF AN EXTRACTION PROCESS FOR PRODUCING ENVIRONMENTAL FRIENDLY AROMATIC RUBBER EXTENDER OIL

以富含芳烃的溶剂精制抽出油为原料,筛选出对多环芳烃具有选择性溶解能力的抽提溶剂,开发了ARE环保型芳烃橡胶填充油抽提工艺,在中型ARE装置上生产出满足欧盟2005/69/EC指令要求的芳烃橡胶填充油。根据中国石化石油化工科学研究院开发的ARE抽提工艺数据包,中国石化济南分公司建设了70 kt/a环保型芳烃橡胶填充油生产装置。生产结果表明,溶剂精制抽出油经ARE溶剂抽提可以生产满足欧盟2005/69/EC指令要求的芳烃橡胶填充油,采用该填充油对橡胶充油后得到的橡胶性能优良,各项指标均达到SBR1723优级品标准。

An extraction process for producing aromatic rubber extender oil was developed and named as ARE process by using a screened out high selective solvent to extract polyeyclic aromatic hydrocarbons from aromatic-rich extracts. On a pilot plant four aromatic-rich extracts were used as feedstocks and relative four aromatic rubber extender oil（ARE oil）samples were obtained. The qualities of these ARE oil samples satisfied the requirements of European Directive 2005/69/EC. Later,an ARE unit with 70 kt/a capacity was set up in SINOPEC Jinan Company based on the ARE extraction process pack- age developed by Research Institute of Petroleum Processing, and the produced environmental friendly ARE oil well met the requirements of European Directive 2005/69/EC. Results of rubber extending oil test showed that the qualities of ARE oil-extended rubber met the super grade specifications of SBR1723 Rubber Standard perfectly.
