Abstract
A process for filtering a liquid stream from a fixed bed reaction zone in order to remove catalyst fines contained in the stream. The effluent stream is passed to a filtering section which may contain at least two filtering vessels. Each filtering vessel includes at least two differently filtering sections, each section designed to collect differently sized particles. If a pressure drop occurs in one of the filtering vessels, it may be taken offline to remove the filtering sections and recover the metal in the particles collected on the filtering sections. The other filtering vessel can remain online to allow the filtering process to be continuous. Metal on the catalyst fines may be recovered.
