Abstract
A separation column for expanded bed adsorption comprises a column tube (), a base () carrying an inlet rotor structure () for pumping in process liquid, and a top cap (). The top cap () is conical in form, and has a peripheral flangeby which it is rigidly fixed to the top edge flange () of the column tube (). The angle of the convergent interior surface () of the conical top cap () may be between 10 and 25°. A vortex-inhibitor component () projects down below the outlet structure () at the top of the cap, projecting into the operating space () of the column to inhibit rotation of liquid in the column interior. An expanded bed adsorption process is done with upward flow of liquid in the column through a bed of media particles.
