Abstract

Abstract: The industrial application of blending deasphaltene oil (DAO) in the feedstocks of 1.7 Mt/a RHT unit was introduced. The operation parameters, feedstocks and product properties, and impurity removal rates were compared before and after blending DAO. The results of application showed that the properties of feedstocks and the impurity removal rates were improved, while the reactor pressure drop was decreased after blending DAO. The addition of DAO plays an active role for long-term cycle length due to the improved FCC feedstocks properties. The overall economic benefits of the company are also increased.

Key words: RHT, DAO, blending, cycle length, economic benefits
