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

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 polycyclic 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 package 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.
