Method and device for synthesis gas generation

Abstract

The invention relates to a method and a device for generation of a crude synthesis gas from a hydrocarbon-containing feed which is at a first pressure and also a steam feed which is at a second pressure that is higher than the first pressure, wherein the hydrocarbon-containing feed and the steam feed are introduced jointly into a reactor and are there reacted at a process pressure that is higher than the first pressure to form the crude synthesis gas. The pressure of at least a part of the hydrocarbon-containing feed is increased before introduction thereof into the reactor using a steam jet pump to which at least a part of the steam feed is fed as motive medium.

1 . A method for generation of a crude synthesis gas from a hydrocarbon-containing feed which is at a first pressure and also a steam feed which is at a second pressure that is higher than the first pressure, wherein the hydrocarbon-containing feed and the steam feed are introduced jointly into a reactor and are there reacted at a process pressure that is higher than the first pressure to form the crude synthesis gas, characterized in that the pressure of at least a part of the hydrocarbon-containing feed is increased before introduction thereof into the reactor using a steam jet pump to which at least a part of the steam feed is fed as motive medium. 
     
     
         2 . The method according to  claim 1 , characterized In that the pressure of the at least one part of the hydrocarbon-containing feed is increased using the steam jet pump to a value which permits the hydrocarbon-containing feed to be introduced into the reactor without further compression. 
     
     
         3 . The method according to  claim 1 , characterized in that the total amount of the hydrocarbon-containing feed is compressed by means of a steam jet pump. 
     
     
         4 . The method according to  claim 1 , characterized in that the total amount of the steam feed is used as motive medium. 
     
     
         5 . The method according to  claim 1 , characterized in that at least the pressure of the part of the steam feed that is provided as motive medium, before introduction thereof into the steam jet pump, is increased to a value which is sufficient to lift the pressure of the hydrocarbon-containing feed to a value sufficient for introduction into the reactor. 
     
     
         6 . The method according to  claim 1 , characterized in that the steam feed is obtained from various sources. 
     
     
         7 . A device for generation of a crude synthesis gas having a reactor, feed appliances for a hydrocarbon-containing feed and a steam feed, and also a compression appliance for elevating the pressure of the hydrocarbon-containing feed, which compression appliance is connected on the exit side to the reactor, characterized in that the compression appliance comprises a steam jet pump that is connected to the feed appliance for the steam feed in such a manner that at least a part of the steam feed is feedable thereto as motive medium. 
     
     
         8 . The device according to  claim 7 , characterized in that the compression appliance consists of exactly one steam jet pump with the aid of which the total amount of the hydrocarbon-containing feed can be compressed to a pressure sufficiently high for introduction thereof into the reactor.
