Abstract: The present invention relates to a process and plant for producing a hydrogen- and carbon oxides-having synthesis gas by partial oxidation of a carbonaceous feedstock having nitrogen compounds. The invention takes advantage of the different solubility of NH3 and CO2 as the synthesis gas stream is cooled. Water is condensed continuously throughout the cooling of the synthesis gas stream. NH3 preferentially dissolves or condenses into the liquid phase during cooling, but at relatively high temperatures, above about 80 to 100° C. Further condensation at lower temperatures then preferentially dissolves or condenses CO2 into the liquid phase. Thus, the formation of ammonium salts during cooling of the synthesis gas is prevented.

Abstract: The invention relates to a partial oxidation reactor (POX reactor) for producing a raw synthesis gas stream by partial oxidation of a carbon-containing input stream in gaseous form, in liquid form or in solid, particulate form dispersed in a carrier liquid or a carrier gas in the presence of an oxygen-containing oxidant stream and optionally a moderator stream containing steam and/or carbon dioxide. The invention further relates to a process for producing a raw synthesis gas stream. The partial oxidation reactor according to the invention provides for introducing a cylindrical or frustoconical inlet region having a constant diameter or a diameter that is smaller on the entrance side. The inlet region is arranged upstream of a cylindrical main reactor portion and represents a bottleneck-like section since the largest diameter of the inlet region is smaller than the diameter of the cylindrical main reactor portion.
