ABSTRACT:
An improved method is disclosed for regenerating adsorbents used in an integrated process for the production of ethers such as methyl tertiary butyl ether by the reaction of an alcohol with an isoolefin. The sorbents are used to remove such compounds as the product ether and the feed alcohol from a hydrocarbon recycle stream withdrawn from the etherification zone. The regeneration procedure includes contacting the sorbent with a portion of the treated hydrocarbon stream. The resultant contaminated hydrocarbon stream is passed into a stripping column used to remove light ends from the effluent of a dehydrogenation zone in which the isoolefin fed to the etherification zone is produced. The hydrocarbonaceous compounds collected on the sorbent are thus recycled rather than being destroyed or lost in low purity effluent streams. The contaminated hydrocarbon stream may also be passed directly into the etherification zone.
