Abstract
An ethanol dehydration process is disclosed. The process comprises adding an amount of steam to a feed to the dehydration reactor to provide a charge stream. The steam stream is mixed with the feed to the dehydration reactor such that the steam to ethanol ratio is between about 0.5 to about 5.0 wt/wt. The charge stream is passed to a dehydration reactor to produce a dehydrated stream. Steam can be imported from outside the dehydration process such as from an oligomerization or dimerization reaction. Steam can be produced from the dehydrated stream.
Claims20
A process for operation of a dehydration reactor comprising adding an amount of steam to a feed to said dehydration reactor wherein said steam is taken from an oligomerization section of a hydrocarbon conversion plant.
A process for operation of a dehydration reactor comprising:
- adding a steam stream to a feed to said dehydration reactor to produce a charge stream;
- dehydrating said charge stream to produce a dehydrated stream;
- cooling said dehydrated stream to separate a water stream;
- and
- producing said steam stream from said separated water stream.
A process for operation of a dehydration reactor, comprising:
- adding a steam stream to a feed to said dehydration reactor to produce a charge stream;
- dehydrating said charge stream to produce a dehydrated stream;
- cooling said dehydrated stream to separate a water stream;
- and
- heating said separated water stream with an olefin charge stream of an oligomerization section to generate said steam stream.
