ABSTRACT:
An integrated process for producing ethers, such as methyl tertiary butyl ether, is disclosed. Specific undesired compounds such as water, methanol or the product ether are removed from a hydrocarbon recycle stream withdrawn from the etherification zone by contacting the recycle stream with a solid regenerable sorbent. Preferably, the sorbent does not remove mono- or diolefinic hydrocarbons from the recycle stream. The treated recycle stream is preferably fractionated to yield isobutane passed into a dehydrogenation zone and normal butane which is charged to a butane isomerization zone.
