Abstract

Die Erfindung betrifft ein Verfahren zur Schwefelgewinnung, bei dem durch Methanolwäsche (M) Schwefelkomponenten und Cyanwasserstoff (HCN) aus einem Syntheserohgas (1) abgetrennt werden, wobei eine erste, HCN-reiche, Schwefelkomponenten enthaltende (3) sowie eine zweite, weitgehend HCN-freie, schwefelreiche Gasfraktion (4) bei der Regenerierung des mit ausgewaschenen Stoffen beladenen Methanolwaschmittels erzeugt und nachfolgend einer Schwefelrückgewinnungsanlage (S) zugeführt werden. Die Erfindung zeichnet sich dadurch aus, dass eine Schwefelrückgewinnungsanlage (S) mit zumindest einer ersten (V1) und einer zweiten Verbrennungszone (V2) eingesetzt wird, wobei zumindest ein Teil der HCN-reichen, ersten Gasfraktion (3) in die erste Verbrennungszone (V1) eingeleitet wird, in der die Ammoniakfracht eines Ammoniak und Schwefelwasserstoff enthaltenden Einsatzgases (5) verbrannt wird.
