    Abstract: A cracked gas, for example as derived from the cracking of ethane under conditions to produce an ethylene gas containing effluent also containing polymers and/or polymerizable constituents, is passed successively through a relatively cheap absorbent or drying material and then through a molecular sieve desiccant. The polymers or polymer-forming constituents are removed from the cracked gases, albeit they are contained therein in very small amount of the order of parts per million. During regeneration of the expensive desiccant bed, the relatively cheap material is discarded as required.
