  • Stripping vessel for removing hydrocarbons entrained in catalyst particles
    Patent number: 9446398
    Abstract: A stripping vessel for removing hydrocarbons from a catalyst and a process for removing hydrocarbons from a catalyst. In an FCC unit, the stripping vessel includes first and second stripping sections. The first stripping section includes at least one grid having a plurality of interesting members and openings therebetween. The second stripping section includes structured packing such as a plurality of ribbons. The one or more grids are spaced from the structured packing, and from each other, so as to minimize the accumulation of catalyst within the stripping vessel, preferably between about 0.91 m (3 ft) to about 1.5 m (5 ft).
