Apparatus and process for separating fluid cracking catalyst particles from flue gas.

摘要

Apparatus suitable for solids-fluid separation (e.g. cracking catalyst/flue gas) comprising a housing (1) provided with outside first stage separation means (6) comprising feed inlet means (2) which cooperate substantially tangentially with a hollow body (16) having solids outlet means (4) in the lower section and fluid outlet means (3) in the upper section communicating with a plurality of annular inlet means of second stage separation means (7) inside the housing, which annular inlet means are provided with swirl imparting means (20) and are defined between the upper sections (11) of a plurality of tubular elements (12) and tubular fluid outlet means (15) of which the lower sections are arranged substantially co-axially within said upper sections and of which tubular fluid outlet means the upper sections cooperate with opening(s) in the upper section of the housing, and solids outlet means cooperating with the lower sections of the tubular elements.
The invention further relates to a process for separating fluid cracking catalyst particles from flue gases and/or hydrocarbon conversion products using said apparatus.
