ABSTRACT:
The present invention comprises a method for separating hydrocarbons from catalyst fines in a slurry oil/catalyst fines/diluent mixture (SCDM) comprising the steps of removing SCDM from a slurry oil storage tank and combining the SCDM with crude oil entering a desalter in order to separate the slurry oil from the catalyst fines, whereby the desalter causes the hydrocarbon content of the SCDM to exit the desalter with dehydrated hydrocarbon from the crude oil while catalyst fines exit the desalter with basic sediment and water removed from the crude oil.
