Abstract
The present invention relates to a system for the separation of suspensions of spent catalysts and hydrocarbons formed in an FCC unit with multiple ascending flow reaction tubes, comprising interconnections between each of the ascending flow reaction tubes and the separator vessel, each interconnection also comprises two sections. The outside sections of the separator vessel are inclined and are connected to a single vertical section, which penetrates into the interior of the separator vessel, and which has at its lower end an open device for draining the spent catalyst from the suspensions separated in this sector. In the same vertical section, at the end of its internal part at the separator vessel, a series of two sets of cyclones are installed, the first set containing cyclones without sealing legs, and the second set containing conventional cyclones of the first stage. The present invention also relates to a process for the separation of suspensions of spent catalysts and hydrocarbons using the said separation system.
