Patent ID: 8029750

Claim:
A process for removal of exhaust gas ( 7 ) which accumulates in the degassing of process condensate in a synthesis gas unit, said synthesis gas unit comprising a steam reformer (D) that is heated from the outside, a flue gas system (K, H) that discharges into the atmosphere oxygen-containing flue gas that accumulates during the heating of the steam reformer (D), and a degasser unit (G) which degasses process condensate and produces the exhaust gas ( 7 ), wherein exhaust gas ( 7 ) contains oxidizable pollutants comprising ammonia and hydrogen and/or carbon monoxide and/or methane and/or methanol and/or organic acids, said process comprising: introducing the exhaust gas ( 7 ) into the flue gas system and mixing, in a reaction zone consisting of gaseous substances, with hot, oxygen-containing flue gas that flows through said flue gas system, wherein the ammonia that is introduced with the exhaust gas ( 7 ) is heated to a temperature of between 600 and 1050° C.
