International ClassC10G 011/18Foreign Application Priority Data1985-10-28 GBAbstractAn apparatus suitable for solids-fluid (e.g. cracking catalyst/hydrocarbon vapor) separation is disclosed having a plurality of substantially vertical tubular elements disposed within a housing. Inlet means are arranged in the bottom section of the housing and communicate with the space between the tubular elements and the housing. A plurality of tubular fluid outlet means are provided, the lower sections of which are arranged substantially coaxially within the upper sections of said tubular elements and define annular spaces therebetween in which swirl imparting means are arranged. The upper sections of the tubular fluid outlet means cooperate with opening(s) in the upper section of the housing, and the lower sections of the tubular elements communicating with solids outlet means. The invention further relates to a process for separating fluid cracking catalyst particles from gaseous hydrocarbon conversion products and/or flue gases using said apparatus.Other References
