Process for separation of water from pyrolysis gasoline

Abstract

A process for separating water from pyrolysis gasoline obtained from a steam cracking step uses a coalescer for the water separation. And a device comprises a coalescer for water separation from pyrolysis gasoline.

1 - 16 . (canceled) 
     
     
         17 . A device comprising at least one coalescer, which is made of metal, fibre glass or a combination of metal and fibre glass, a water separation unit and at least one hydrogenation unit. 
     
     
         18 . The device according to  claim 17 , wherein the water separation unit is connected to the coalescer (A) and the coalescer (A) is connected to a first hydrogenation unit, which in turn is connected with the coalescer (B) followed by a second hydrogenation unit, wherein the coalescer (A) or the coalescer (B) is made of metal, fibre glass or a combination of metal and fibre glass. 
     
     
         19 . A method for the separation of water from pyrolysis gasoline which comprises employing the device according to  claim 17  to separate water from pyrolysis gasoline. 
     
     
         20 . The method according to  claim 19 , wherein the coalescer is made of metal.
