摘要： Provided is a process for producing a synthesis gas product stream by partial oxidation of fluid or fluidizable carbon-containing feed stream with an oxygen-containing oxidant in a partial oxidation reactor (106) by at least partially reacting the feed stream in a reaction chamber (108) to afford a hot crude synthesis gas stream, quenching the hot crude synthesis gas stream in a quench chamber (112) arranged downstream of an outlet of the reaction chamber (108) to form a quenched crude synthesis gas stream, discharging a purified synthesis gas stream from at least one conditioning stage and/or purification stage (118), cooling the purified synthesis gas stream with a first coolant stream and introducing into a gas-liquid phase separation apparatus (126) to discharge a synthesis gas product stream and an ammonia-containing liquid condensate stream and at least partially recycling the ammonia-containing liquid condensate stream to the quench chamber (112).

摘要： The present invention relates to a process and plant for producing a hydrogen- and carbon oxides-comprising synthesis gas by partial oxidation of a carbonaceous feedstock comprising 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.
