Abstract

A process and apparatus for continuously purifying gases by removing entrained burdening substances therefrom, wherein the gas is loaded with entrained substances is passed substantially radially through adsorbing material arranged about an axis of rotation as an adsorber bed, the substances being retained on the adsorbing materials in the course of their rotational movement about the axis of rotation, and in the course of further rotational movement the load of retained substances is desorbed, optionally after inertization, by flushing with a fluid medium, e.g., hot gases or steam, and the adsorbing material may then be cooled and/or dried. Rotational movement is preferably done intermittently, and the feed stream to and the drain stream from the adsorbing material each are conducted through a confined space extending at least in one direction substantially parallelly to the axis of rotation or to the adsorber bed, the confined space being fed and drained axially. The direction of the feed stream is at least essentially opposite to that of the drain stream in relation to the adsorber bed.
