摘要： An apparatus suitable for solids-fluid separation (e.g. cracking catalyst/flue gas) is disclosed in which a housing encloses a first stage separation means which includes a feed inlet means which cooperate substantially tangentially with a hollow body having solids outlet means in its lower section. A fluid outlet means communicates with the hollow body with a plurality of annular inlet means of a second stage separation means. The annular inlet means are provided with swirl imparting means and are defined between the upper sections of a plurality of tubular elements and tubular fluid outlet means arranged such that the lower sections of the tubular fluid outlet means are substantially coaxial within the upper sections of the tubular members and the upper sections of the tubular fluid outlet means communicate with opening(s) in the upper section of the housing. Solids outlet means communicate 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.

摘要： An apparatus is disclosed for the separation of solids from a mixture of solids and fluid, comprising a housing defining a plurality of separation chambers, each chamber being arranged around a central longitudinal axes and having a curved inner wall such that the intersection of the inner wall and a plane perpendicular to the central longitudinal axes is a concave line, whereby all central longitudinal axes are in one plane, and each chamber having an inlet opening, a solids outlet opening and at least one fluid outlet opening, whereby each fluid outlet opening is in communication with a fluid outlet conduit, and whereby the solids outlet opening of each chamber is in communication with a solids outlet conduit which is in tangential cooperation with the chamber, which apparatus further comprises one supply conduit for the mixture of fluid and solids whereby the supply conduit debouches into a supply opening that is formed by the combined inlet openings of all chambers which openings are communicating with each other, and in which apparatus the supply opening and the solids outlet openings are arranged at the same side of the plane of the central longitudinal axes of the separation chambers.
