Abstract
A method for dehydration of a gas stream is disclosed. The method comprises contacting an oxygenate containing gas stream with a water stream in a contactor column to absorb the oxygenate and provide a washed gas stream. The washed gas stream is contacted with a first adsorbent in a first adsorbent layer to adsorb the oxygenate to provide a first contacted gas stream. The first contacted gas stream is contacted with a second adsorbent in a second adsorbent layer to adsorb water and provide a dehydrated gas stream.
Claims21
A method for dehydration of a gas stream, comprising:
- contacting an oxygenate containing gas stream with a water stream in a contactor column to absorb the oxygenate and provide a washed gas stream;
- contacting said washed gas stream with a first adsorbent in a first adsorbent layer to adsorb the oxygenate to provide a first contacted gas stream;
- and
- contacting said first contacted gas stream with a second adsorbent in a second adsorbent layer to adsorb water and provide a dehydrated gas stream.
A method for dehydration of a gas stream, comprising:
- contacting a carbon dioxide rich gas stream comprising alcohol with a water stream in a contactor column to absorb the alcohol and provide a washed carbon dioxide rich gas stream;
- contacting said washed carbon dioxide rich gas stream with a first adsorbent in a first adsorbent layer to adsorb the alcohol to provide a contacted carbon dioxide rich gas stream;
- and
- contacting said contacted carbon dioxide rich gas stream with a second adsorbent in a second adsorbent layer to adsorb water to provide a dehydrated carbon dioxide rich gas stream.
A method for dehydration of a gas stream, comprising
- contacting an alcohol containing gas stream with water in a contactor column to absorb the oxygenate and provide a washed gas stream;
- contacting said washed gas stream with a first adsorbent in a first adsorbent layer to adsorb the alcohol to provide a first contacted gas stream, the first adsorbent comprising one or more of an amorphous silica gel, an amorphous aluminosilicate, an activated alumina, or an activated carbon;
- and
- contacting said first contacted gas stream with a second adsorbent in a second adsorbent layer to adsorb water to provide a dehydrated gas stream, the second adsorbent comprising a zeolite.
