Abstract:

The technological characteristics，industrial application and operation results of the 3rd generation ethylbenzene technology from FCC dry gas are described，which was developed by DICP and is currently operated in a styrene combined unit in North China Petrochemical Company（the first system of the heat medium at the bottom of the benzene tower）. The results showed that this technology is a green，flexible，economic and advanced route for FCC dry gas up grading and EB production.
