Abstract:
1. An apparatus for improving flow properties of crude, comprising: a riser charged with catalyst and having a bottom and a top, wherein a crude conduit delivers a first crude stream into said bottom and spent catalyst and a vaporized cracked stream exit from said top; a vessel in downstream communication with said riser containing a cyclone for receiving and separating said vaporized cracked stream from said spent catalyst; a fractionator in downstream communication with said vessel for receiving said vaporized cracked stream and fractionating a naphtha stream; an absorber for scrubbing hydrogen sulfide from light ends downstream of the fractionator; a hydrotreating reactor in downstream communication with said fractionator for receiving at least portion of said naphtha stream, said hydrotreating reactor also in communication with said absorber; and a conduit carrying a second crude stream in downstream communication with said hydrotreater for receiving a hydrotreated naphtha into said second crude stream.
