Ausscheidungsvorrichtung

摘要

A separation process comprises passing a gas or vapour stream contaminated with an undesired substance or contaminant downwardly through a plurality of spiral separating media such that the direction of movement of the gas or vapour stream is transversely the longitudinal axes of at least some of the spiral separating media. The undesired substance or contaminant is allowed to separate from the gas or vapour as it passes through the bed, and purified gas or vapour is withdrawn from the bed.
