Abstract
A separation process comprises passing a gas or vapor 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 vapor 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or contaminant is allowed to separate from the gas or vapor as it passes through the bed, and purified gas or vapor is withdrawn from the bed.
