ABSTRACT:
The present invention is a process for removing catalyst fines from a reactor effluent stream that has catalyst fines therein. The process comprises withdrawing the reactor effluent stream from the reactor. The reactor effluent stream is transported in a first conduit to a quench device and is quenched to form a quenched effluent stream and a liquid fraction containing a majority of the catalyst fines. The liquid fraction is transported in a second conduit to a solids separation device. The conditions under which the catalyst fines are moved prevent accumulation of catalyst fines in the catalyst fines process steps.
