Abstract
A process and related apparatus for separating particulate solids from a stream comprising vapors and particulate solids passed in admixture through an elongated contacting zone. The stream is discharged downwardly at an angle to the vertical along the inside wall of a cylindrical disengagement zone and at an angle to the horizontal of greater than 0.degree. and less than 45.degree.. The solids separate due to centripetal acceleration and fall to the bottom of the disengagement zone.

A process for separating particulate solids from a stream comprising vapors and particulate solids passed in admixture through a vertically elongated contacting zone, which process comprises discharging said stream from said contacting zone downwardly into the main body of a disengagement zone, said disengagement zone having an interior cylindrical surface, the cylindrical axis of which is substantially vertical, altering the direction of flow of said stream upon the discharge of said stream from said contacting zone by deflection means so as to effect the flow of said stream to be in a downward direction along the curvature of said interior surface, said stream having a downward progression while maintaining a helical twist about a vertical axis, whereby said solids fall to a bottom portion of said disengagement zone and said vapors rise to an upper portion thereof, the angle of direction of flow of said stream from said deflection means to the horizontal being greater than 0.degree. and less than 45.degree..
An apparatus useful for separating particulate solids from a stream comprising vapors and particulate solids in admixture, said apparatus comprising in combination:
- (a) a vertical riser conduit having a discharge opening through which said stream may pass;
- (b) a cylindrical vessel containing said discharge opening, the cylindrical axis of said vessel being vertical and said opening discharging into the main body of the vessel;
- and,
- (c) a deflecting means comprising a curved surface juxtaposed with respect to said discharge opening such that said stream passing from said discharge opening is deflected in a downward direction along the curvature of the interior surface of said vessel, and wherein the angle of direction of flow of said stream from said deflecting means to the horizontal is greater than 0.degree. and less than 45.degree., said deflecting means providing a downward progression to said stream while maintaining a helical twist about a vertical axis.
