24.3 Ethyl-ether is produced by the dehydration of ethanol over a suitable catalyst 2C2H5OH → (C2H5)2O + H2O The feed to the process (F) is industrial ethanol containing 12 % water and 3 % methanol (CH3OH). It is mixed with a recycle stream (R) and charged to the reactor. The methanol content of the reactor feed stream (A) must be limited to 9.8 %. The reactor product stream is passed through two separators. In the first separator all the ethyl-ether is recovered as pure ethyl-ether (E). In the second separator a part of the water is recovered as pure water (W). The second separator also yields the recycle stream, consisting of a mixture of ethanol, methanol and water containing 70 % ethanol and 15 % methanol. To limit the methanol content in the feed to the reactor, part of this stream is purged (P). A schematic representation of the process is shown.
